PCMSK0 – Pin Change Mask Register A
PCMSK1 – Pin Change Mask Register B
• Bits 7:0 – PCINT7:0: 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 PCIE1 bit in GIMSK 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.
• Bits 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 PCINT11:8 is set and the PCIE0 bit in GIMSK is set, pin change interrupt is enabled on
the corresponding I/O pin, and if PCINT15:12 is set and the PCIE1 bit in GIMSK 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.
