enabled
Port A GPIO — This GPIO pin can be individually programmed as
an input or output pin.
ANA2 and VREFHA and CMPA_M1 — Analog input to channel 2 of
ADCA and analog references high of ADCA and negative input 1 of
analog comparator A.
When used as an analog input, the signal goes to ANA2 and
VREFHA and CMPA_M1. ADC control register configures this input
as ANA2 or VREFHA.
After reset, the default state is GPIOA2.

ANA3 and VREFLA and CMPA_M2 — Analog input to channel 3 of
ADCA and analog references low of ADCA and negative input 2 of
analog comparator A.
When used as an analog input, the signal goes to ANA3 and
VREFLA and CMPA_M2. ADC control register configures this input
as ANA3 or VREFLA.
After reset, the default state is GPIOA3.
