MDCHODIS MDCHPOL MDCHSYNC

— MDCH<3:0>

bit 7 bit 0

Legend:

R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’

u = Bit is unchanged x = Bit is unknown -n/n = Value at POR and BOR/Value at all other Resets

‘1’ = Bit is set ‘0’ = Bit is cleared

bit 7

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

bit 6

MDCHPOL: Modulator High Carrier Polarity Select bit

1 = Selected high carrier signal is inverted

0 = Selected high carrier signal is not inverted

bit 5 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

low time carrier

0 = Modulator Output is not synchronized to the high time carrier signal

(1)

bit 4 Unimplemented: Read as ‘0’

bit 3-0

MDCH<3:0> Modulator Data High Carrier Selection bits

(1)

1111 = Reserved. No channel connected.

•

0101 = Reserved. No channel connected.

0100 = CCP1 output (PWM Output mode only)

0011 = Reference Clock module signal (CLKR)

0010 = MDCIN2 port pin

0001 = MDCIN1 port pin

0000 =V

Note 1: Narrowed carrier pulse widths or spurs may occur in the signal stream if the carrier is not synchronized.
