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:
Selects which PWM channel is output to OUT_A
Bits D17–D16:
Selects which PWM channel is output to OUT_B
Bits D13–D12:
Selects which PWM channel is output to OUT_C
Bits D09–D08:
Selects which PWM channel is output to OUT_D
Note that channels are encoded so that channel 1 = 0x00, channel 2 = 0x01, …, channel 4 = 0x03.
