How does one disable/re-enable serial RX interrupts on a nRF51822 ?

Hello,

How is this done for a nRF51822? Below is an example for LPC1768, KL25Z and K64F (assuming UART0):

void PcRxIRQcallback(void){
    pcRxIRQCnt++;
#if defined(TARGET_KL25Z)
    NVIC_DisableIRQ(UART0_IRQn);        // n=0, 1 or 2  Disable Rx interrupt on kl25z
#endif
#if defined(TARGET_K64F)
    NVIC_DisableIRQ(UART0_RX_TX_IRQn);  // n=0, 1 or 2  Disable Rx interrupt on k64f
#endif
#if defined(TARGET_LPC1768)
    LPC_UART0->IER = 0;                 //Disable Rx interrupt on mbed1768
#endif

    while (pc.readable()) {
        inchar = pc.getc();             //read data from USB
        PcRxChar(inchar);               //go process char
    }

#if defined(TARGET_KL25Z)
    NVIC_EnableIRQ(UART0_IRQn);         // n=0, 1 or 2  Re-enable Rx interrupt on kl25z
#endif
#if defined(TARGET_K64F)
    NVIC_EnableIRQ(UART0_RX_TX_IRQn);   // n=0, 1 or 2  Re-enable Rx interrupt on k64f
#endif
#if defined(TARGET_LPC1768)
    LPC_UART0->IER = 1;                 //RE-enable Rx interrupt on mbed1768
#endif
}
