Legend:
R = Readable bit
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
CMIDL: Stop in Idle Mode bit
1 = When device enters Idle mode, module does not generate interrupts. Module is still enabled
0 = Continue normal module operation in Idle mode
1 = When device enters Idle mode, module does not generate interrupts. Module is still enabled
0 = Continue normal module operation in Idle mode
bit 14
Unimplemented: Read as ‘0’
