corresponding Interrupt Vector. The flag is cleared when the interrupt routine is executed. Alter-
natively, the flag can be cleared by writing a logical one to it.
• 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.
• 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.
