PCMSK0 – Pin Change Mask Register 0
• Bits 7:3 – Res: Reserved Bits
These bits are reserved and will always read as zero.
• Bits 2..0 – PCINT10..8: Pin Change Enable Mask 10..8
Each PCINT10..8 bit selects whether pin change interrupt is enabled on the corresponding I/O
pin. If PCINT10..8 is set and the PCIE1 bit in GIMSK is set, pin change interrupt is enabled on
the corresponding I/O pin. If PCINT10..8 is cleared, pin change interrupt on the corresponding
I/O pin is disabled.
• 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 PCIE0 bit in GIMSK is set, pin change interrupt is enabled on the
corresponding I/O pin. If PCINT7..0 is cleared, pin change interrupt on the corresponding I/O pin
is disabled.
