Hello everyone.


I'm using MCU KE04 series and I want write a register of CPU


For instance, the KBI0_PE (Pin Enable Register) can be found in 0x40079000 absolute address so, Can't i do this?



//////////////////////////////////////////////////////////////////////// CODE ////////////////////////////////////////////////////////////////////////

static const uint32_t BASE_ADDRESS_KBI0 = 0x40079000; //Base address
uint32_t *pointerRegister = NULL; //Initialization


pointerRegister = (BASE_ADDRESS_KBI0 + 8); //points to location fo KBI0_SC (40079008h)
*pointerRegister = 0xFEFFFFFF; //¿Write register?


it frozen MCU, why?¿
