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 AMPEN: Op Amp x Control Module Enable bit
1 = Module is enabled
0 = Module is disabled
bit 14 Unimplemented: Read as ‘0’
bit 13 AMPSIDL: Op Amp x Peripheral Stop in Idle Mode bit
1 = Discontinues module operation when device enters Idle mode
0 = Continues module operation in Idle mode
bit 12 AMPSLP: Op Amp x Peripheral Enabled in Sleep Mode bit
1 = Continues module operation when device enters Sleep mode
0 = Discontinues module operation in Sleep mode
bit 11-8 Unimplemented: Read as ‘0’
bit 7 SPDSEL: Op Amp x Power/Speed Select bit
1 = Higher power and bandwidth (faster response time)
0 = Lower power and bandwidth (slower response time)
bit 6 Unimplemented: Read as ‘0’

bit 2-0 PINSEL<2:0>: Positive Op Amp Input Select bits
111 = Op amp positive input is connected to the output of the A/D input multiplexer
110 = Reserved; do not use
101 = Op amp positive input is connected to the DAC1 output for OA1 (DAC2 output for OA2)
100 = Reserved; do not use
011 = Reserved; do not use
010 = Op amp positive input is connected to the OAxINC pin
