Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 15-8 Unimplemented: Read as ‘0’
bit 7 SODIS: Modulation Source Output Disable bit
(1)
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 MS<3:0> Modulation Source Selection bits
