void digConfig(char statemask);
Configures channels PIO0 to PIO3 on the A/D converter to allow them to be used as digital I/O via
header JP4 on the RCM3700 Prototyping Board.
Remember to execute the brdInit function before calling this function to prevent a runtime error.
PARAMETER
statemask is a bitwise mask representing JP4 channels 1 to 4. Use logic 0 for inputs and logic 1 for
outputs in these bit positions:
bits 7–5—0
bit 4—JP4:4
bit 3—JP4:3
bit 2—JP4:2
bit 1—JP4:1
bit 0—0
RETURN VALUE
None.
