The 8/16-bit PPG output reverse register (REVC) reverses the PPG output
including the initial level.
■ Register Configuration
■ Register Functions
[bit7:6] Undefined bits
Their read values are always "0". Writing values to these bits has no effect on operation.
[bit5] REV21: PPG timer 21 (ch. 2) output level reverse bit
This bit selects the output level of PPG timer 21 (ch. 2).
[bit4] REV20: PPG timer 20 (ch. 2) output level reverse bit
This bit selects the output level of PPG timer 20 (ch. 2).
[bit3] REV11: PPG timer 11 (ch. 1) output level reverse bit
This bit selects the output level of PPG timer 11 (ch. 1).
[bit2] REV10: PPG timer 10 (ch. 1) output level reverse bit
This bit selects the output level of PPG timer 10 (ch. 1).
