13.2.7 PCMSK2 – Pin Change Mask Register 2

• Bit 7:0 – PCINT23:16: Pin Change Enable Mask 23:16

Each PCINT23:16-bit selects whether pin change interrupt is enabled on the corresponding I/O

pin. If PCINT23:16 is set and the PCIE2 bit in PCICR is set, pin change interrupt is enabled on

the corresponding I/O pin. If PCINT23:16 is cleared, pin change interrupt on the corresponding

I/O pin is disabled.

13.2.8 PCMSK1 – Pin Change Mask Register 1

• Bit 7 – Res: Reserved

This bit is reservedand will always read as zero.

• Bit 7:0 – PCINT15:8: Pin Change Enable Mask 15:8

Each PCINT15:8-bit selects whether pin change interrupt is enabled on the corresponding I/O

pin. If PCINT15:8 is set and the PCIE1 bit in PCICR is set, pin change interrupt is enabled on the

corresponding I/O pin. If PCINT15:8 is cleared, pin change interrupt on the corresponding I/O

pin is disabled.

13.2.9 PCMSK0 – Pin Change Mask Register 0

• Bit 7:0 – PCINT[7:0]: Pin Change Enable Mask 7:0

Each PCINT7:0 bit selects whether pin change interrupt is enabled on the corresponding I/O pin.

If PCINT7:0 is set and the PCIE0 bit in PCICR is set, pin change interrupt is enabled on the cor-

responding I/O pin. If PCINT7::0 is cleared, pin change interrupt on the corresponding I/O pin is

disabled.
