2 Configuration of the Integrated Operational Amplifiers

This section describes how to set up the MSP430FR2311 control registers to enable the integrated operational amplifiers as general-purpose operational amplifiers. There are two steps in setting up an integrated OA to work as a general-purpose OA.

  • Enable and configure the OA module.
  • Configure the pin multiplexing to enable required OA functions on the external pins.
