what does MPU_InitStruct.TypeExtField ? mean only three options available #define MPU_TEX_LEVEL0 ((uint8_t)0x00)#define MPU_TEX_LEVEL1 ((uint8_t)0x01)#define MPU_TEX_LEVEL2 ((uint8_t)0x02)does it mean only 3 set of HAL_MPU_ConfigRegion(&MPU_InitSt...

hi @Danish ,Thanks for your response.Please find the exampleuint32 reset_status = 0; reset_status = READ_BIT(RCC->RSR, RCC_RSR_PORRSTF); if(reset_status==0x00800000) // POWER on reset {}Please not its important to deinit and clear all the flags bef...
