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: 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.
