PCMSK0 – Pin Change Mask Register 0
• Bit 7:0 – PCINT[11:4]: Pin Change Enable Mask 15:8
These bits select whether pin change interrupt is enabled on the corresponding I/O pin. If
PCINT[11:4] is set and the PCIE1 bit in EIMSK is set, pin change interrupt is enabled on the cor-
responding I/O pin. If PCINT[11:4] is cleared, pin change interrupt on the corresponding I/O pin
is disabled.
• Bits 7:4 – Reserved
These bits are reserved in the Atmel ATmega16HVB/32HVB, and will always read as zero.
• Bit 3:0 – PCINT[3:0]: Pin Change Enable Mask 3:0
Each PCINT[3:0] bit selects whether pin change interrupt is enabled on the corresponding I/O
pin. If PCINT[3:0] is set and the PCIE0 bit in PCICR is set, pin change interrupt is enabled on the
corresponding I/O pin. If PCINT[3:0] is cleared, pin change interrupt on the corresponding I/O
pin is disabled.
