Interrupt service routine
On receiving an interrupt, system software should:
Read InterruptStatus
If (GPIO.bit==1)
{
Read InterruptStatusGPIO
Write InterruptStatus to clear the corresponding bit
}
If (PWM.bit==1)
{
Read InterruptStatusPWM
Write InterruptStatus to clear the corresponding bit
}
If ( EV_ALARM or TOUCHSCREEN or TOUCHKEY or RE1/2)
{
}
Process INT
Write InterruptStatus to clear the corresponding bit
Process GPIO INT
Write InterruptStatusGPIO to clear the corresponding bit
Process PWM INT
Write InterruptStatusPWM to clear the corresponding bit
