How to use FPU to actively trigger IDC interrupt #175

Closed loatwith closed 4 weeks ago

loatwith commented 1 month ago

Hi I want to test the fpu interrupt in syscfg_cfgr1 of stm32g431

SYSCFG configuration register 1 (SYSCFG_CFGR1)

FPU_IE[5]: Inexact interrupt enable FPU_IE[4]: Input denormal interrupt enable FPU_IE[3]: Overflow interrupt enable FPU_IE[2]: underflow interrupt enable FPU_IE[1]: Divide-by-zero interrupt enable FPU_IE[0]: Invalid operation interrupt enable

I am very confused about how to trigger the Input denormal interrupt（FPU_IE[4]）

I am waiting for your answer
