Hi,

I am trying to set and then read back interupt priorities in my LPC1226 project  they all seem to read back as zero, is this normal?

    ui32interupt_priority [0] = NVIC_GetPriority (TIMER_16_0_IRQn) ;
    ui32interupt_priority [1]= NVIC_GetPriority (TIMER_32_1_IRQn) ;
    ui32interupt_priority [2]= NVIC_GetPriority (UART0_IRQn) ;
    NVIC_SetPriority(TIMER_16_0_IRQn, 0xC0);
    NVIC_SetPriority(UART0_IRQn, 0x80);
    NVIC_SetPriority(UART0_IRQn, 0x40);
    ui32interupt_priority [0] = NVIC_GetPriority (TIMER_16_0_IRQn) ;
    ui32interupt_priority [1]= NVIC_GetPriority (TIMER_32_1_IRQn) ;
    ui32interupt_priority [2]= NVIC_GetPriority (UART0_IRQn) ;
