Hi,

I try to write a interrupt function with registers on the stm32h743zi referans manual ,but keil doesn't recognize some registers for exp ,EXTI->CPUPR1 =(1<<13); SYSCFG->EXTICR4= (1<<5);

stm32cubeh7 MCU package V1.5

Perhaps go look at the definitions for the structures, see if the registers are lists or have subtly different naming.

android autocomplete, not good for fat fingered dyslexics..

Look into the CMSIS-mandated device header ([Cube]\Drivers\CMSIS\Device\ST\[Family]\Include\[device].h) how are these peripherals (EXTI, SYSCFG) defined.

ST is not famous for rigorously matching the registers/bitfiled names between RM and the headers.
