I have been away from learning the ST32 for a good while and just coming back to it. I am using the NUCLEO-L073 board (uses the STM32L073) and setting up the GPIO module. Looking into the online videos (not for this chip) it mentons setting up the AHB bus, but I cant see it in the data sheet for the GPIO. I have attached the page with the block diagram, where I can see a bus connecting them, but doesnt mention an AHB. Am I correct in thinking I simply set up the IO pins and there isnt a bus to setup, or am I missing something?
