I am using pin P1.25 on an LPC1759 as a Match Register output pin. The documentation shows only 3 functions for that pin, with MAT1 as the third. However, I set it as IOCON_FUNC2 (third function), I get no output. I get expected output on that pin if I set it to IOCON_FUNC3 with the function:
Chip_IOCON_PinMuxSet(pIOCON, 1, 25, IOCON_MODE_INACT | IOCON_FUNC3);
What am I missing?
Thanks in Advance - james
