STM32G051C8Tx: I am having issue setting up the global interrupt on I2C1. I am not able to find the EXTI 23 in the STM32CubeMx. It only shows up to EXTI 15. 

I am using the gpio interrupt (EXTI) and trying to tie with SPP1. Only EXTI4_TRG and EXTI9_TRG are defined in stm32u5xx_hal_spi_ex.h for group1. Is that possible to define EXTI11_TRG in the group1?
