Legend:
R = Readable bit
-n = Value at POR
r = Reserved bit
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⁾
1 = Auto-scan is enabled
0 = Auto-scan is disabled
LPEN: Low-Power Enable bit
1 = Returns to Low-Power mode after scan
0 = Remains in Full-Power mode after scan
CTMREQ: CTMU Request bit
1 = CTMU is enabled when the A/D is enabled and active
0 = CTMU is not enabled by the A/D
BGREQ: Band Gap Request bit
1 = Band gap is enabled when the A/D is enabled and active
0 = Band gap is not enabled by the A/D
Reserved: Maintain as ‘0’
Unimplemented: Read as ‘0’
ASINT<1:0>: Auto-Scan (Threshold Detect) Interrupt Mode bits
11 = Interrupt after a Threshold Detect sequence has completed and a valid compare has occurred
10 = Interrupt after a valid compare has occurred
01 = Interrupt after a Threshold Detect sequence has 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 the CMx and ASINTx bits, occurs)
01 = Convert and save (conversion results are saved to locations as determined by the register bits when
a match, as defined by the CMx bits, occurs)
00 = Legacy operation (conversion data is saved to a location determined by the 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 the value in the corresponding buffer
register)
00 = Less Than mode (valid match occurs if the result is less than the value in the corresponding buffer register)
Note 1: When using auto-scan with Threshold Detect (ASEN = 1), do not configure the sample clock source to
Auto-Convert mode (SSRC<3:0> = 7). Any other available SSRC selection is valid. To use auto-convert as
the sample clock source (SSRC<3:0> = 7), make sure ASEN is cleared.
