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

ASEN: Auto-Scan Enable bit
1 = Auto-scan is enabled
0 = Auto-scan is disabled
LPEN: Low-Power Enable bit
1 = Return to Low-Power mode after scan
0 = Remain in Full-Power mode after scan
CTMREQ: CTMU Request bit
1 = CTMU is enabled when the ADC is enabled and active
0 = CTMU is not enabled by the ADC
BGREQ: Band Gap Request bit
1 = Band gap is enabled when the ADC is enabled and active
0 = Band gap is not enabled by the ADC
VRSREQ: VREG Scan Request bit
1 = On-chip regulator is enabled when the ADC is enabled and active
0 = On-chip regulator is not enabled by the ADC
Unimplemented: Read as ‘0’
ASINT<1:0>: Auto-Scan (Threshold Detect) Interrupt Mode bits
11 = Interrupt after Threshold Detect sequence completed and valid compare has occurred
10 = Interrupt after valid compare has occurred
01 = Interrupt after Threshold Detect sequence completed
00 = No interrupt
Unimplemented: Read as ‘0’
WM<1:0>: Write Mode bits
11 = Reserved
10 = Auto-compare only (conversion results are not saved, but interrupts are generated when a valid
match, as defined by CM and ASINT bits, occurs)
01 = Convert and save (conversion results are saved to locations as determined by register bits when
a match, as defined by CM bits, occurs)
00 = Legacy operation (conversion data saved to location determined by buffer register bits)
CM<1:0>: Compare Mode bits
11 = Outside Window mode (valid match occurs if the conversion result is outside of the window defined by
the corresponding buffer pair)
10 = Inside Window mode (valid match occurs if the conversion result is inside the window defined by the
corresponding buffer pair)
01 = Greater Than mode (valid match occurs if the result is greater than value in the corresponding buffer
register)
00 = Less Than mode (valid match occurs if the result is less than value in the corresponding buffer register)
