PCMSK0 – Pin Change Mask Register 0
• Bits 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 GIMSK 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.
