PCMSK0 – Pin Change Mask Register 0
• Bit 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 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.
