8285E–AVR–02/2013
Bit 0 – INTF0: External Interrupt Flag 0
When an edge or logic change on the INT0 pin triggers an interrupt request, INTF0 becomes set (one). If the I-bit in
SREG and the INT0 bit in EIMSK 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.
This flag is always cleared when INT0 is configured as a level interrupt.

PCMSK3 – Pin Change Mask Register 3 (1)
Note:
1. PCMSK3 and PCMSK2 are only present in Atmel ATmega3250A/3250PA/6450A/6450P.
Bit 6:0 – PCINT30:24: Pin Change Enable Mask 30:24
Each PCINT30:24-bit selects whether pin change interrupt is enabled on the corresponding I/O pin. If PCINT30:24
is set and the PCIE3 bit in EIMSK is set, pin change interrupt is enabled on the corresponding I/O pin. If
PCINT30:24 is cleared, pin change interrupt on the corresponding I/O pin is disabled.
13.2.5
PCMSK2 – Pin Change Mask Register 2 (1)
Note:
1. PCMSK3 and PCMSK2 are only present in ATmega3250A/3250PA/6450A/6450P.
Bit 7:0 – PCINT23:16: Pin Change Enable Mask 23:16
Each PCINT23:16 bit selects whether pin change interrupt is enabled on the corresponding I/O pin. If PCINT23:16
is set and the PCIE2 bit in EIMSK is set, pin change interrupt is enabled on the corresponding I/O pin. If
PCINT23:16 is cleared, pin change interrupt on the corresponding I/O pin is disabled.
13.2.6
PCMSK1 – Pin Change Mask Register 1
Bit 7:0 – PCINT15:8: Pin Change Enable Mask 15:8
Each PCINT15:8-bit selects whether pin change interrupt is enabled on the corresponding I/O pin. If PCINT15:8 is
set and the PCIE1 bit in EIMSK is set, pin change interrupt is enabled on the corresponding I/O pin. If PCINT15:8
is cleared, pin change interrupt on the corresponding I/O pin is disabled.
13.2.7
PCMSK0 – Pin Change Mask Register 0
Bit 7:0 – PCINT7:0: Pin Change Enable Mask 7:0
Each PCINT7:0 bit selects whether pin change interrupt is enabled on the corresponding I/O pin. If PCINT7:0 is set
and the PCIE0 bit in EIMSK is set, pin change interrupt is enabled on the corresponding I/O pin. If PCINT7:0 is
cleared, pin change interrupt on the corresponding I/O pin is disabled.
