29.4.1 Enabling the Op Amp

Each Op Amp has its own enable signal. This is controlled by the AMPEN bit in the AMPxCON1 register. Upon Reset, AMPEN is set to ‘0’. This keeps all of the Op Amp instances disabled upon Reset. To enable instance x of the op amp, set the AMPEN bit to ‘1’ in the AMPxCON1 register.
