13.3.4 PCMSK3 – Pin Change Mask Register 3
(1)
• 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.
13.3.5 PCMSK2 – Pin Change Mask Register 2
(1)
• 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.
13.3.6 PCMSK1 – Pin Change Mask Register 1
Note: 1. PCMSK3 and PCMSK2 are only present in the Atmel ATmega3290A/3290PA/6490A/6490P.
• 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.
13.3.7 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.
