REGISTER 23-2:

MDSRC: MODULATION SOURCE CONTROL REGISTER

R/W-x/u

U-0

R/W-x/u

MDMSODIS

—

MDMS<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

MDMSODIS:

Modulation Source Output Disable bit

1 = Output signal driving the peripheral output pin (selected by MDMS<3:0>) is disabled
0 = Output signal driving the peripheral output pin (selected by MDMS<3:0>) is enabled

bit 6-4

Unimplemented:

Read as ‘0’

bit 3-0

MDMS<3:0>

Modulation Source Selection bits

0001 = MDMIN port pin
0000 = MDBIT bit of MDCON register is modulation source

Note 1:

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