4.4 BL2000 Function APIs

4.4.1 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 and DAC calibration constants from flash memory into SRAM for use by your pro-
gram.

The ports are initialized as follows:
