MDCLODIS: Modulator Low Carrier Output Disable bit
1 = Output signal driving the peripheral output pin (selected by MDCL<3:0> of the MDCARL register)
is disabled
0 = Output signal driving the peripheral output pin (selected by MDCL<3:0> of the MDCARL register)
is enabled
MDCLPOL: Modulator Low Carrier Polarity Select bit
1 = Selected low carrier signal is inverted
0 = Selected low carrier signal is not inverted
MDCLSYNC: Modulator Low Carrier Synchronization Enable bit
1 = Modulator waits for a falling edge on the low time carrier signal before allowing a switch to the high
time carrier
0 = Modulator output is not synchronized to the low time carrier signal(1)
Unimplemented: Read as â0â
MDCL<3:0> Modulator Data High Carrier Selection bits (1)
1111 = Reserved. No channel connected.

1000 = Reserved. No channel connected.
0111 = CCP4 output (PWM Output mode only)
0110 = CCP3 output (PWM Output mode only)
0101 = CCP2 output (PWM Output mode only)
0100 = CCP1 output (PWM Output mode only)
0011 = Reference clock module signal
0010 = MDCIN2 port pin
0001 = MDCIN1 port pin
0000 = VSS
Note 1: Narrowed carrier pulse widths or spurs may occur in the signal stream if the carrier is not synchronized.
