WG_OUTPUT
WG_OUTPUT (Port 6)
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.

Output Polarity
These bits select the output polarity of the port 6 pins.
0 = active-low outputs
1 = active-high outputs
Reserved; for compatibility with future devices, write zero to this bit.
Mode
These bits select either the peripheral function or general-purpose
output function of the port 6 pins. Clear these bits for general-purpose
output.
