This flag is cleared by writing a one to it.
This flag is set when EXTINTx pin matches the external interrupt sense configuration and will generate an
interrupt request if INTENCLR/SET.EXTINT[x] is one.
Writing a zero to this bit has no effect.
Writing a one to this bit clears the External Interrupt x flag.
