9223F–AVR–04/14
13.2.6 PCMSK2 – Pin Change Mask Register 2
Bit 7:0 – PCINT[23:16]: Pin Change Enable Mask 23...16
Each PCINT[23:16]-bit selects whether pin change interrupt is enabled on the corresponding I/O pin. If PCINT[23:16] is set
and the PCIE2 bit in PCICR is set, pin change interrupt is enabled on the corresponding I/O pin. If PCINT[23:16] is cleared,
pin change interrupt on the corresponding I/O pin is disabled.
13.2.7 PCMSK1 – Pin Change Mask Register 1
Bit 7 – Reserved
This bit is an unused bit in the Atmel ATmega48PA/88PA/168PA, and will always read as zero.
Bit 6:0 – PCINT[14:8]: Pin Change Enable Mask 14...8
Each PCINT[14:8]-bit selects whether pin change interrupt is enabled on the corresponding I/O pin. If PCINT[14:8] is set and
the PCIE1 bit in PCICR is set, pin change interrupt is enabled on the corresponding I/O pin. If PCINT[14:8] is cleared, pin
change interrupt on the corresponding I/O pin is disabled.
13.2.8 PCMSK0 – Pin Change Mask Register 0
Bit 7:0 – PCINT[7:0]: Pin Change Enable Mask 7...0
Each PCINT[7:0] bit selects whether pin change interrupt is enabled on the corresponding I/O pin. If PCINT[7:0] is set and
the PCIE0 bit in PCICR is set, pin change interrupt is enabled on the corresponding I/O pin. If PCINT[7:0] is cleared, pin
change interrupt on the corresponding I/O pin is disabled.
