4.4.2 Board Initialization
Call this function at the beginning of your program. This function initializes the system I/O ports and
loads all the A/D converter and D/A converter calibration constants from flash memory into SRAM for
use by your program. If the LCD/keypad module is installed, this function will turn off LED DS1 to indi-
cate that the initialization was successful.
Summary of Initialization
LP3500 uses main oscillator
LCD/keypad module buffer is disabled
RS-485 serial communication is not enabled
RS-232 serial communication is enabled
Unused configurable inputs are tied and unused configurable outputs are set low
Self-timed chip select is set to 109 ns
If A/D converter chip is installed, chip is reset and SCLKD is set to 19,200 bps
If A/D converter chip is installed, calibration constants are read
If relay is installed, relay is set to NC or RESET position
The ports are initialized according to Table A-3.
void brdInit (void);
