Legend:
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 ASEN: Auto-Scan Enable bit
1 = Auto-scan is enabled
0 = Auto-scan is disabled
bit 14 LPEN: Low-Power Enable bit
1 = Low power is enabled after scan
0 = Full power is enabled after scan
bit 13 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
bit 12 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
bit 11-10 Unimplemented: Read as ‘0’
bit 9-8 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
bit 7-4 Unimplemented: Read as ‘0’
bit 3-2 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 occurs, as defined by the CM and ASINT bits)
01 = Convert and save (conversion results are saved to locations as determined by the register bits
when a match occurs, as defined by the CM bits)
00 = Legacy operation (conversion data is saved to a location determined by the buffer register bits)
bit 1-0 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)
