(P1MATCH & P1MASK). This allows Software to be notified if a certain change or pattern occurs on P0 or
P1 input pins regardless of the XBRn settings. A port match event can cause an interrupt if EMAT (EIE2.1)
is set to '1' or cause the internal oscillator to awaken from SUSPEND mode. See Section “

Write - Output appears on I/O pins per Crossbar Registers.
0: Logic Low Output.
1: Logic High Output (high impedance if corresponding P0MDOUT.n bit = 0).
Read - Always reads ‘0’ if selected as analog input in register P0MDIN. Directly reads Port
pin when configured as digital input.
0: P0.n pin is logic low.
1: P0.n pin is logic high.
Port pins configured as analog inputs have their weak pullup, digital driver, and digital
receiver disabled.
0: Corresponding P0.n pin is configured as an analog input. In order for the P0.n pin to be
in analog input mode, there MUST be a '1' in the Port Latch register corresponding to
that pin.
1: Corresponding P0.n pin is not configured as an analog input.
