MDCHODIS
R/W-x/u
Narrowed carrier pulse widths or spurs may occur in the signal stream if the carrier is not synchronized.
MDCHODIS: Modulator High Carrier Output Disable bit
1 = Output signal driving the peripheral output pin (selected by MDCH<3:0>) is disabled
0 = Output signal driving the peripheral output pin (selected by MDCH<3:0>) is enabled
MDCHPOL: Modulator High Carrier Polarity Select bit
1 = Selected high carrier signal is inverted
0 = Selected high carrier signal is not inverted
MDCHSYNC: Modulator High Carrier Synchronization Enable bit
1 = Modulator waits for a falling edge on the high time carrier signal before allowing a switch to the
0 = Modulator Output is not synchronized to the high time carrier signal
Unimplemented: Read as ‘0’
