These bits are unused bits in the Atmel
zero.
When the PCIE2 bit is set (one) and the I-bit in the Status Register (SREG) is set (one),
pin change interrupt 2 is enabled. Any change on any enabled PCINT23..16 pin will cause
an interrupt. The corresponding interrupt of Pin Change Interrupt Request is executed
from the PCI2 Interrupt Vector. PCINT23..16 pins are enabled individually by the PCMSK2
Register.
When the PCIE1 bit is set (one) and the I-bit in the Status Register (SREG) is set (one),
pin change interrupt 1 is enabled. Any change on any enabled PCINT14..8 pin will cause
an interrupt. The corresponding interrupt of Pin Change Interrupt Request is executed
from the PCI1 Interrupt Vector. PCINT14..8 pins are enabled individually by the PCMSK1
Register.
When the PCIE0 bit is set (one) and the I-bit in the Status Register (SREG) is set (one),
pin change interrupt 0 is enabled. Any change on any enabled PCINT7..0 pin will cause an
interrupt. The corresponding interrupt of Pin Change Interrupt Request is executed from
the PCI0 Interrupt Vector. PCINT7..0 pins are enabled individually by the PCMSK0
Register.
These bits are unused bits in the Atmel ATA6612/ATA6613, and will always read as zero.
When a logic change on any PCINT23..16 pin triggers an interrupt request, PCIF2
becomes set (one). If the I-bit in SREG and the PCIE2 bit in PCICR are set (one), the
MCU will jump to the corresponding Interrupt Vector. The flag is cleared when the interrupt
routine is executed. Alternatively, the flag can be cleared by writing a logical one to it.
