Read/Write
These bits are unused bits in the ATA6602/ATA6603, and will always read as 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 ATA6602/ATA6603, 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 exe-
cuted. Alternatively, the flag can be cleared by writing a logical one to it.
When a logic change on any PCINT14..8 pin triggers an interrupt request, PCIF1 becomes
set (one). If the I-bit in SREG and the PCIE1 bit in PCICR are set (one), the MCU will jump to
the corresponding Interrupt Vector. The flag is cleared when the interrupt routine is exe-
cuted. Alternatively, the flag can be cleared by writing a logical one to it.
