The port 6 output configuration (WG_OUTPUT) register controls port 6 functions. If you are using port
6 for general-purpose outputs, write C0H (for active-high outputs) or 00H (for active-low outputs) to
the high byte of WG_OUTPUT, and write the desired pin values to the low byte. If you are using port 6
for waveform generator or PWM outputs, please refer to Chapter 9, “Waveform Generator” or Chapter
10, “Pulse-width Modulator” for a description of the WG_OUTPUT register functions.
