• Bit 7..0 – PCINT15..8: Pin Change Enable Mask 15..8
Each PCINT15..8 bit selects whether pin change interrupt is enabled on the correspond-
ing I/O pin. If PCINT15..8 is set and the PCIE1 bit in GICR 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 correspond-
ing I/O pin. If PCINT7..0 is set and the PCIE0 bit in GICR 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.
The mapping between I/O pins and PCINT bits can be found in Figure 1 on page 2. Note
that the Pin Change Mask Register are located in Extended I/O. Thus, the pin change
interrupts are not supported in ATmega161 compatibility mode.
