bit 7 bit 0
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 ADRC: A/D Conversion Clock Source bit
1 = RC clock
0 = Clock derived from system clock
bit 14 EXTSAM: Extended Sampling Time bit
1 = A/D is still sampling after SAMP = 0
0 = A/D is finished sampling
bit 13 Reserved: Maintain as ‘0’
