2.3OPAMP Control Register

The OPAMP control register (OPCR) is used to turn on and off the OPAMP, to enable and disable OPAMP analog output, and to enable and disable OPAMP analog input.

The register can also be used to set the OPAMP to operate as a standalone open loop operational amplifier, or a non-inverting closed loop operational amplifier with six different closed loop gain settings that can be selected by the software.
