Port B GPIO — This GPIO pin can be individually programmed as
an input or output pin.
ANB0 and CMPB_P2 — Analog input to channel 0 of ADCB and
positive input 2 of analog comparator B.
When used as an analog input, the signal goes to ANB0 and
CMPB_P2.
After reset, the default state is GPIOB0.

ANB1 and CMPB_M0— Analog input to channel 1 of ADCB and
negative input 0 of analog comparator B.
When used as an analog input, the signal goes to ANB1 and
CMPB_M0.
After reset, the default state is GPIOB1.

ANB2 and VREFHB and CMPC_P2 — Analog input to channel 2 of
ADCB and analog references high of ADCB and positive input 2 of
analog comparator C.
When used as an analog input, the signal goes to ANB2 and
VREFHB and CMPC_P2. ADC control register configures this input
as ANB2 or VREFHB.
After reset, the default state is GPIOB2.

ANB3 and VREFLB and CMPC_M0 — Analog input to channel 3 of
ADCB and analog references low of ADCB and negative input 0 of
analog comparator C.
When used as an analog input, the signal goes to ANB3 and
VREFLB and MPC_M0. ADC control register configures this input
as ANB3 or VREFLB.
After reset, the default state is GPIOB3.
