WG_OUTPUT (Port 6)
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.

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.
Data
In general-purpose output mode, these bits hold the values to be driven
out on the pins. Write the desired values to these bits (bits 7:0
correspond to pins P6.7:0).
