bit 7 bit 0
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 Control Module Enable bit
1 = Module is enabled
0 = Module is disabled
bit 14 Unimplemented: Read as ‘0’
bit 13 AMPSIDL: Op Amp 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 Peripheral Enabled in Sleep Mode bit
1 = Continues module operation when device enters Sleep mode
0 = Discontinues module operation in Sleep mode
bit 11-10 INTPOL<1:0>: Interrupt Mode Select bits
When CMPSEL =
1:
11 = Interrupt occurs on any change
10 = Interrupt occurs on negative edge
01 = Interrupt occurs on positive edge
00 = Interrupts are disabled
When CMPSEL =
0:
Op amp interrupts are not generated.
bit 9 CMOUT: Comparator Mode Output State bit
When CMPSEL =
1:
1 = Non-inverting input is greater than the inverting input
0 = Non-inverting input is less than the inverting input
When CMPSEL =
0:
Op Amp mode (no digital state information is generated).
bit 8 CMPSEL: Op Amp Mode Select bit
1 = Configured as a comparator
0 = Configured as an op amp
bit 7 SPDSEL: Op Amp/Comparator Power/Speed Select bit
1 = Higher power and bandwidth (faster response time)
0 = Lower power and bandwidth (slower response time)
bit 6 AMPOE: Amplifier Output Enable bit
1 = Amplifier or comparator output is sent to OAxOUT pin
0 = Amplifier or comparator output is not sent to OAxOUT (pin is controlled by TRISx and LATx bits)
