When a logic change on any PCINT12..8/7..0 pin triggers an interrupt request, PCIF1/0
becomes set (one). If the I-bit in SREG and the PCIE1/0 bit in PCICR are set (one), the MCU will
jump to the corresponding Interrupt Vector. The flag is cleared when the interrupt routine is exe-
cuted. Alternatively, the flag can be cleared by writing a logical one to it.
12.0.7
Pin Change Mask Register 0 – PCMSK0
• 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
corresponding I/O pin. If PCINT7..0 is cleared, pin change interrupt on the corresponding I/O pin
is disabled.
12.0.8
Pin Change Mask Register 1– PCMSK1
• Bit 4..0 – PCINT12..8: Pin Change Enable Mask 12..8
Each PCINT12..8 bit selects whether pin change interrupt is enabled on the corresponding I/O
pin. If PCINT12..8 is set and the PCIE1 bit in PCICR is set, pin change interrupt is enabled on
the corresponding I/O pin. If PCINT12..8 is cleared, pin change interrupt on the corresponding
I/O pin is disabled.
