PA0_C/PA1_C/PC2_C/PC3_C[STM32H743XGH6]

PA0_C/PA1_C/PC2_C/PC3_C
What is the base address for the above four GPIOs that can be set?

Also, do you have the following understanding about the above 4 pins?
Pxy_C can be set to a pin of the same function or another function by controlling an analog switch.

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

    Thank you very much.

    I understand, there is no separate configuration register for Pxy_C, you are talking about whether or not it is connected via a switch to the Pxy's pins.
