UICR writing issue

[IMRAN]

Hi team,

I am using nRF5_SDK_15.3.0_59ac345 and nrf52832 controller. I am using nRF5_SDK_15.3.0_59ac345/examples/ble_peripheral/ble_app_uart example code and the hardware contains a button on long-press we need to write button status in the UICR register for the future purpose. 

I disabled softdevice with nrf_sdh_disable_request(); but I am stuck there itself I am not able to get what is happening over there. can you please help me out with this problem. the below code snippet I am using. if possible can you please send me an example snippet.

void on_button_press_write()

{

nrf_sdh_disable_request();

uint32_t sleep_state_read = 0;

uint32_t sleep_state_write = 1;

NRF_NVMC->CONFIG = NVMC_CONFIG_WEN_Wen << NVMC_CONFIG_WEN_Pos;

nrf_delay_ms(100);

while (NRF_NVMC->READY == NVMC_READY_READY_Busy){}

nrf_delay_ms(100);

*(uint32_t *)0x100010E8 = sleep_state_write ;

nrf_delay_ms(100);

NRF_NVMC->CONFIG = NVMC_CONFIG_WEN_Ren << NVMC_CONFIG_WEN_Pos;

nrf_delay_ms(100);

while (NRF_NVMC->READY == NVMC_READY_READY_Busy){}

nrf_delay_ms(100);

sleep_state_read = *(uint32_t *)0x100010E8;

sd_nvic_SystemReset();

}
