FUNCTION
PWM OUTPUT MUX REGISTER (0x25)
This DAP output mux selects which internal PWM channel is output to the external pins. Any channel can be
output to any external output pin.
Bits D21–D20:
Bits D17–D16:
Bits D13–D12:
Bits D09–D08:
Selects which PWM channel is output to OUT_A
Selects which PWM channel is output to OUT_B
Selects which PWM channel is output to OUT_C
Selects which PWM channel is output to OUT_D
Note that channels are enclosed so that channel 1 = 0x00, channel 2 = 0x01, channet 1 = 0x02, and channel 2 =
0x03.
