3. Verify EPROM from address OOOOH against RAM buffer address range 1000 2FFFH Description The Verify Eprom command allows the user to verify that the contents of the eprom are the same as the RAM buffer This command essentially compares the eprom with the RAM buffer and indicates where they differ The parameters are structured in a manner identical to the Program Eprom command form 1 of this command is used then the entire eprom is verified against the RAM buffer starting at eprom address OOOOH and RAM address OOOOH A number of bytes equal to the size of the eprom are compared If form 2 is used then the user may specify a sub range of the RAM buffer to be compared to the eprom starting at the user specified address If either form is selected a panel similar to the following is displayed Eprom type is 27256 Eprom size is 8000H Ram start address is 0000H Ram end address is 7FFFH Eprom start address is 0000H Number of bytes to verify 8000H Proceed with Verifying Y N The values listed in each line may differ depending on the parameters the user typed in and the type of eprom which has previously been selected using the Type command The user may now decide to either abort or proceed with the verify Only the responses Y or N are accepted If the user aborts then the Serial Eprom Programmer prompt appears and the user is 42 returned to the command line If the user proceeds with the verify th

5. 27512 27C512 FFFFH When an eprom address is allowed or required for a command the user may specify any address from OOOOH through to the maximum address for the current eprom type the eprom type which was selected with the Type command If the user attempts to specify an eprom address which is greater than the Maximum Address then the error message Eprom address is out of range will appear and the user will be returned to the command line Obviously this message will not appear if the current eprom type is 27512 or 27C512 as all 4 digit hex addresses are valid for those types 2 6 Auto baud Feature Immediately after power up or reset the Serial Eprom Programmer performs some self tests and then waits for the user to enter a carriage return This carriage return is used to determine what baud rate the host computer or terminal is using When the baud rate has been recognized the following power up logo is displayed FEAE aE aE AE AE E a aE ae AE AE E aE aE a aaa aaa Serial Eprom Programmer Firmware Version 2 00 Copyright C Perrier Technologies Apr 17th 1993 HEHEHE EE EEE HEE EE EEE HE EEE HE EEE EH EE HEF Note that the baud rate of the computer or terminal must have been one of 600 1200 2400 4800 9600 or 19200 baud If it wasn t then the Serial Eprom Programmer will keep waiting for a Carriage return at one of those baud rates After the power up logo appears the Serial Eprom Programmer p
6. 32Kb or 64Kb RAM buffer is used rather extensively Most of the commands involve the RAM buffer For example the user can download data into or upload data from the RAM buffer using the Download and Upload commands respectively The user may also modify the RAM buffer using the Edit RAM Buffer Fill RAM Buffer or Move commands The user also has the ability to search for a pattern in the RAM buffer using the Search Buffer command The user may view the contents of the RAM buffer using the Display RAM Buffer command The user may also work with the eprom in the ZIF socket The user must first select the current eprom type using the Type command The contents of the eprom may then be viewed using the Display Eprom command The user may also perform a blank test on the eprom to ensure that it is blank contains only FF data bytes using the Blank Test command The eprom may also be searched for a byte pattern using the Search Eprom command The user may then program bytes from the RAM buffer into the eprom using the Program Eprom command or copy bytes from the eprom into the RAM buffer using the Copy command As well the user can compare that the contents of the eprom are the same as the RAM buffer using the Verify command In addition to all of these commands the user may request help or perform diagnostics on the Serial Eprom Programmer hardware 1 6 Firmware Updates Firmware updates will be supplied as a separate eprom The current fir
7. 4 eproms are required Similarly a 16 bit download is required when the target system has a 16 bit data bus The lt format gt parameter is the only non optional parameter It specifies the format that the downloaded data will be in The format is one of e INT Intellec 26 e XOR Exorcisor e HASC Hex ASCII e BIN Binary e DBIN Dec Binary For details on each of these formats see Appendix A The byte select parameter is optional If it is not specified then it is assumed to be 0 Note that if other parameters are specified the RAM start address or the RAM end address then the byte select must be specified If the previous word size parameter was 8 or not specified then the byte select must be 0 If word size is 16 then byte select may be one of 0 or 1 If word size is 32 then byte select may be one of 0 1 2 or 3 For 16 and 32 bit downloads byte select determines which half or quarter of the incoming data to keep For example if word size is 16 and byte select is 0 then data bytes at an even file address would be kept If byte select were 1 then data bytes at an odd file address would be kept If word size is 32 then if byte select is 0 data bytes whose file address mod 4 is O would be kept If byte select is 1 then data bytes whose file address mod 4 is 1 would be kept A similar criteria is used for byte select of 2 and 3 Thus one can see that if a 32 bit download were b
8. Addresses Several of the commands allow the user to enter a RAM address A RAM address is a hexadecimal number of maximum length 4 digits The minimum RAM address is OOOOH Depending on how much RAM is installed in the Serial Eprom Programmer the maximum RAM address will differ This table indicates the maximum allowed RAM address for the amount of RAM installed Amount of RAM Installed Maximum RAM Address 32 Kb 7FFFH 64 Kb FFFFH When a RAM address is allowed or required for a command the user may specify any address from OOOOH through to the maximum address If the user attempts to specify a RAM address which is greater than the maximum allowed RAM address then the following error message appears Ram address is out of range and the user is returned to the command line Serial Eprom Programmer Prompt Obviously this message will never appear if 64Kb of RAM are installed because every 4 digit hexadecimal address will be in range 2 5 Eprom Addresses Several of the commands allow the user to enter an eprom address An eprom address is a hexadecimal number of maximum length 4 digits The minimum eprom address is OOOOH Depending on the type of eprom being used the maximum eprom address will differ The following table indicates the maximum eprom address for the allowed types of eproms Eprom Type Maximum Address 2716 27C16 O7FFH 2732 2732A 27C32 OFFFH 2764 2764A 27C64 1FFFH 27128 27128A 27C128 3FFFH 27256 27C256 7FFFH

10. The Serial Eprom Programmer also has either 32Kb or 64Kb of on board static RAM which is used as a buffer between the eprom and the host computer The user will typically download data into this RAM buffer from the host computer or terminal and then program the data in the RAM buffer into the eprom Similarly the user can copy data from the eprom into the RAM buffer and then upload this data to the host computer 1 2 Scope This document describes the capabilities of the Serial Eprom Programmer Firmware Version 2 00 A full description is given of the normal operation and of the commands provided in Firmware Version 2 00 In addition a description is given of the various download formats which are supported by Firmware Version 2 00 1 3 Exclusions This document does not attempt to e Describe the sequence of steps necessary to assemble the Serial Eprom Programmer e Detail features which may be included in future releases of the Serial Eprom Programmer firmware e Detail the hardware or describe the circuitry of the Serial Eprom Programmer 1 4 Legal Waiver No responsibility is assumed for damage to eproms or to the Serial Eprom Programmer due to carelessness or improper use by the user 1 5 Serial Eprom Programmer Capabilities This section very briefly outlines the capabilities of the Serial Eprom Programmer A more detailed description of each of the commands may be found in Section 3 As was Stated in Section 1 1 the
