Pin Change
Interrupt Enable 2
When the PCIE2 bit
is set and the I-bit in the Status Register (SREG) is set, pin change interrupt 2 is
enabled. Any change on any enabled PCINT[23:16] pin will cause an interrupt. The
corresponding interrupt of Pin Change Interrupt Request is executed from the PCI2
Interrupt Vector. PCINT[23:16] pins are enabled individually by the PCMSK2
Register.
Pin Change
Interrupt Enable 1
When the PCIE1 bit
is set and the I-bit in the Status Register (SREG) is set, pin change interrupt 1 is
enabled. Any change on any enabled PCINT[14:8] pin will cause an interrupt. The
corresponding interrupt of Pin Change Interrupt Request is executed from the PCI1
Interrupt Vector. PCINT[14:8] pins are enabled individually by the PCMSK1
Register.
Pin Change Interrupt Enable 0
When the PCIE0 bit
is set and the I-bit in the Status Register (SREG) is set, pin change interrupt 0 is
enabled. Any change on any enabled PCINT[7:0] pin will cause an interrupt. The
corresponding interrupt of Pin Change Interrupt Request is executed from the PCI0
Interrupt Vector. PCINT[7:0] pins are enabled individually by the PCMSK0
Register.
