• Bit 7:1 – PCINT15:9 - Pin Change Enable Mask
Bits 15:9 of the PCMSK1 register have no function in this device. The I/O ports
associated to PCINT15:9 are not implemented.
• Bit 0 – PCINT8 - Pin Change Enable Mask 8
If this bit is set to one the pin change interrupt on the corresponding I/O pin is enabled.
If this bit is set to zero the pin change interrupt is disabled.

Each bit PCINT7:0 selects whether the pin change interrupt is enabled on the
corresponding I/O pin. If PCINT7:0 is set and the PCIE0 bit in PCICR is set, the pin
change interrupt is enabled on the corresponding I/O pin. If PCINT7:0 is cleared, the pin
change interrupt on the corresponding I/O pin is disabled.
