Definition:

#include <aGPM.tea>




void aGPM_SetPortBits(

char addr, char dir);

Parameters:

addr	-	IIC address of the specified GPM.
dir	-	State bits for the digital IO pins configured as outputs.

Return Value:

This routine does not return a value.

Description:

This routine sets the output state bits of the digital IO pins that have been configured as outputs on a GPM.  The lower 4 bits are the output state bits.  Setting a bit makes the corresponding pin high.  Clearing a bit makes the corresponding pin low.  See the documentation for the GPS Module for more details regarding GPM registers and functions.

Example:

#include <aGPM.tea>

aGPM_SetPortBits((unsigned char)0xD0, 0x03);


This would turn on digital outputs 0 and 1 and turn off digital outputs 2 and 3 on the GPM.
