interrupt is enabled by clearing the X mask bit in the CPU Condition Code register. The I/O state of the
pin is forced to input level upon the first clearing of the X bit and held in this state even if the bit is set
again. A STOP or WAIT recovery with the X bit set (refer to CPU12/CPU12X Reference Manual) is not
available.

enabled ECLKX2 signal forces the I/O state to an output.
100 LQFP: ECLKX2 > GPO
If the Autonomous Periodic Interrupt clock is enabled and routed here the I/O state is forced to output.
