SFR Definition 17.14. P1MASK: Port1 Mask

Bits 7–0: P1MASK[7:0]: Port1 Mask Value.

These bits select which Port pins will be compared to the value stored in P1MAT.

0: Corresponding P1.n pin is ignored and cannot cause a Port Match event.

1: Corresponding P1.n pin is compared to the corresponding bit in P1MAT.

SFR Definition 17.15. P2: Port2

Bits 7–0: P2.[7:0]

Write - Output appears on I/O pins per Crossbar Registers.

0: Logic Low Output.

1: Logic High Output (high impedance if corresponding P2MDOUT.n bit = 0).

Read - Always reads ‘0’ if selected as analog input in register P2MDIN. Directly reads Port

pin when configured as digital input.

0: P2.n pin is logic low.

1: P2.n pin is logic high.
