The Quadrature Decoders are clocked by the output of Timer A10 giving a maximum clock rate of one half of the peripheral clock rate The time constant of Timer A10 must be fast enough to sample the inputs properly Both the I and Q inputs go through a digital fil ter that rejects pulses shorter than two clock periods wide In addition the clock rate must be high enough that transitions on the I and Q inputs are sampled in different clock cycles The Input Capture see the Rabbit 3000 Microprocessor Users Manual may be used to measure the pulse width on the I inputs because they come from the odd numbered port bits The operation of the digital filter is shown below Peri Clock Timer A10 146 RabbitCore RCM3209 RCM3229 The Quadrature Decoder generates an interrupt when the counter increments from 0x00 to 0x01 or when the counter decrements from 0x00 to OxFF Note that the status bits in the QDCSR are set coincident with the interrupt and the interrupt and status bits are cleared by reading the QDCSR Table E 5 Quadrature Decoder Registers Register Name Mnemonic Address Quad Decode Control Status QDCSR 10010000 0x90 Register Bit Value Description 7 0 Quadrature Decoder 2 did not increment from OxFF rd only I Quadrature Decoder 2 incremented from OxFF to 0x00 This bit is cleared by a read of this register

The RJ 45 connector is shielded to minimize EMI effects to from the Ethernet signals The Ethernet chip supports auto MDI MDIX on the Ethernet port to choose the Ethernet interface automatically based on whether a crossover cable or a straight through cable is used in a particular setup The Ethernet chip may spike the current draw by up to 200 mA while it is searching to determine the type of Ethernet cable This search is repeated every second if no Ethernet cable is detected If you do not plan to connect an Ethernet cable use the Dynamic C pd_powerdown function call to turn off the Ethernet chip The pd powerup function call is available to turn the Ethernet chip back on at a later time These function calls are described in the Dynamic C TCP IP User s Manual Volume 1 User s Manual 27 4 2 3 Serial Programming Port The RCM3209 RCM3229 serial programming port is accessed using header J1 or over an Ethernet connection via the RabbitLink EG2110 The programming port uses the Rabbit 3000 s Serial Port A for communication Dynamic C uses the programming port to down load and debug programs The programming port is also used for the following operations e Cold boot the Rabbit 3000 on the RCM3209 RCM3229 after a reset e Remotely download and debug a program over an Ethernet connection using the RabbitLink EG2110 e Fast copy designated portions of flash memory from one Rabbit based board the master to another the slave

The RabbitCore design presumes that the voltage regulator is on the user board and that the power is made available to the RCM3209 RCM3229 board through header J62 An RCM3209 RCM3229 with no loading at the outputs operating at 29 4 MHz typically draws 145 mA The RCM3209 RCM3229 will consume an additional 10 mA when the programming cable is used to connect the programming header J1 to a PC D 1 1 Battery Backup The RCM3209 RCM3229 does not have a battery but there is provision for a customer supplied battery to back up the data SRAM and keep the internal Rabbit 3000 real time clock running Header J62 shown in Figure D 1 allows access to the external battery This header makes it possible to connect an external 3 V power supply This allows the SRAM and the inter nal Rabbit 3000 real time clock to retain data with the RCM3209 RCM3229 powered down External Battery 30 VBAT_EXT 3 3 VIN 31 32 GND Figure D 1 External Battery Connections at Header J2 User s Manual 135 A lithium battery with a nominal voltage of 3 V and a minimum capacity of 165 mA h is recommended A lithium battery is strongly recommended because of its nearly constant nominal voltage over most of its life The drain on the battery by the RCM3209 RCM3229 is typically 12 uA when no other power is supplied If a 165 mA h battery is used the battery can last almost 2 years 165 mA h 12 uA The actual life in your ap

131. unction Calls 5 2 1 Digital I O The RCM3209 RCM3229 was designed to interface with other systems and so there are no drivers written specifically for the I O The general Dynamic C read and write func tions allow you to customize the parallel I O to meet your specific needs For example use WrPortI PEDDR amp PEDDRShadow 0x00 to set all the Port E bits as inputs or use WrPortI PEDDR amp PEDDRShadow 0xFF to set all the Port E bits as outputs When using the external I O bus on the Rabbit 3000 chip add the line define PORTA AUX IO required to enable external I O bus to the beginning of any programs using the external I O bus The sample programs in the Dynamic C SAMPLES RCM3200 directory provide further examples 5 2 2 SRAM Use The RCM3209 RCM3229 has a battery backed data SRAM and a program execution SRAM Dynamic C provides the protected keyword to identify variables that are to be placed into the battery backed SRAM The compiler generates code that creates a backup copy of a protected variable before the variable is modified If the system resets while the protected variable is being modified the variable s value can be restored when the system restarts The sample code below shows how a protected variable is defined and how its value can be restored protected nf device nandFlash int main _sysIsSoftReset restore any protected variables The bbram keyword may also be used instead if there is a n
