Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown

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