ATmega162/V

2513E–AVR–09/03

Pin Change Mask Register 1 –

PCMSK1

• 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.

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 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.
