1: An interrupt condition has been detected on the corresponding pin.
0: No interrupt condition has beedn detected on the corresponding pin since reset or the last time it was cleared.
The number of interrupt request lines is dependant on the number of I/O pins on the MCU. Refer to the product specific data for
details. Note also that a bit in the Interrupt Flag register is only valid if the corresponding bit in IER is set.
