You need to perform a System Reset after writing to the UICR registers in order for the changes to take affect, i.e.

    NRF_NVMC->CONFIG = NVMC_CONFIG_WEN_Wen << NVMC_CONFIG_WEN_Pos;
    while (NRF_NVMC->READY == NVMC_READY_READY_Busy){}
    NRF_UICR->PSELRESET[0] = 21;
    while (NRF_NVMC->READY == NVMC_READY_READY_Busy){}
    NRF_UICR->PSELRESET[1] = 21;
    while (NRF_NVMC->READY == NVMC_READY_READY_Busy){}
    NRF_NVMC->CONFIG = NVMC_CONFIG_WEN_Ren << NVMC_CONFIG_WEN_Pos;
    while (NRF_NVMC->READY == NVMC_READY_READY_Busy){}
    NVIC_SystemReset();
