Port M general-purpose input/output data—Data Register
When not used with an alternative signal, the associated pin can be used as general-purpose I/O. In
general-purpose output mode the port data register bit value is driven to the pin.
If the associated data direction bit is set to 1, a read returns the value of the port data register bit, otherwise the
buffered pin input state is read.
