5.2.4 Prototyping Board Function Calls
The functions described in this section are for use with the Prototyping Board features.
The source code is in the RCM34xx.LIB library in the Dynamic C LIB\RCM3400 folder if
you need to modify it for your own board design.
Other generic functions applicable to all devices based on Rabbit microprocessors are
described in the Dynamic C Function Reference Manual .
5.2.5 Board Initialization
void brdInit (void);
Call this function at the beginning of your program. This function initializes Parallel Ports A through G
for use with the RCM3400 Prototyping Board.
Summary of Initialization
1. Display/keypad select is disabled.
2. Ethernet select is disabled.
3. RS-485 is not enabled.
4. RS-232 is not enabled.
5. Unused configurable I/O are tied inputs or outputs set low.
6. A/D converter is reset and SCLKB is set to 57,600 bps.
7.A/D converter calibration constants are read, so this function cannot run in RAM.
RETURN VALUE
None.
