8. the Programming phase The Erase phase does not involve further data transfer from the host PC and will occur relatively quickly The Programming phase involves the transfer of the user s program that is to be put into the flash The Total Time to Program entries in the table are computed as Minimum Total Time to Program KB to program Time to Transfer 1 KB Time to Connect The reason the above is labeled Minimum Total Time to Program is because it neglects the time needed to actually erase and program each bit in the flash As a data point the F2808FlashTest out file i e 64KB size was programmed into a F2808 at 9600 baud and observed to take 4 0 minutes from start to finish compared with 3 4 minutes in the table The data in the table was compiled using a 2 1 MHz Pentium PC running Windows XP SP2 The PC speed is not expected to be a factor in determining the programming times however a User Options 4 Erase acknowledge retry specifier After sending the DSP an erase command the PC runs a loop that checks for an erase acknowledge from the DSP This option controls the maximum number of times the PC will loop It is generally best to make this option large e g 500 is the default value which gives the DSP plenty of time to erase the flash SDFlash will complete the erase operation as soon as the DSP reports that it is finished In SDFlash Serial versions prior to v3 0 the user would specify a fixed amount of
