WG_OUTPUT (Port 6)

Address:

1FC0H

 

Reset State:

0000H

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

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.
