3.5.4.1 AGPIO Filter

In order to help reduce noise for the analog portion of AGPIO pins, a configurable filter is available. This filter can be enabled and configured in two banks. For more details on the two groups of AGPIO filters and configuration options available, see the AGPIO and ANALOG_SUBSYS_REGS sections of each device-specific TRM.
