Hi, I want to use the p0.18 as a GPIO without being connected to nRESET function. So I removed "CONFIG_GPIO_AS_PINRESET" from the define option in Keil. And then i found that the reset value of PSELRESET was still been set as 0x0012 when I debugged the example project. Is the datasheet wrong? And then I try to set PSELRESET as:
while (NRF_NVMC->READY == NVMC_READY_READY_Busy){}
NRF_UICR->PSELRESET[0] = 0xffffffff;
while (NRF_NVMC->READY == NVMC_READY_READY_Busy){}
NRF_UICR->PSELRESET[1] = 0xffffffff;
But it doesdn't work, the value of the PSELRESET still is 0x0012.
So i want to known how to change the PSELRESET to be 0xffffffff. Thank you.
