Nucleo H723ZG registers for GPIO's (?)

[Lysandros]

Hello,

I have a general question to the pin mapping and registers for the H723ZG. 

Where can I find the register name or register ID of e.g. the GPIO PA4? I expect something like 0000x000 or similar.

I have searched for this in the DB3171 Data Brief, in the RM0468 Reference Manual and in the UM2407 User Manual (with pin-out), but this GPIO and other aren't even mentioned in the manual...So how do I access these functions, if I can't find the register numbers?

Thank you 

Kind regards

Hello,

Not sure what do you mean by "the register name or register ID of e.g. the GPIO PA4? I expect something like 0000x000 or similar."!

The register names are available in the RM0468 rev 3 / starting from the page 518 section: 11.4 GPIO registers.

There is no register for each GPIO pin.

@Lysandros Individual GPIO pins do not have registers. GPIOs come in blocks of 16: GPIOA, GPIOB and so on. Each block has 16 pins and set of registers.
