Legend:
R = Readable bit
U = Unimplemented bit
W = Writable bit
P = Programmable bit
-n = Bit Value at POR: (‘0’, ‘1’, x = Unknown)
r = Reserved bit

bit 7-5
Reserved: Write ‘0’; ignore read
ON: ADC Operating Mode bit
1 = A/D converter module is operating
0 = A/D converter is off
FRZ: Freeze in Debug Exception Mode bit
1 = Freeze operation when CPU enters Debug Exception mode
0 = Continue operation when CPU enters Debug Exception mode
Note: FRZ is writable in Debug Exception mode only. It reads ‘0’ in Normal mode.
SIDL: Stop in Idle Mode bit
1 = Discontinue module operation when device enters Idle mode
0 = Continue module operation in Idle mode
Reserved: Write ‘0’; ignore read
