62 / 364 page  62 8023F–AVR–07/09 ATmega325P/3250P 12.3.4 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. 12.3.5 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. Note: 1. PCMSK3 and PCMSK2 are only present in ATmega3250P. 12.3.6 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. 12.3.7 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 cor- responding I/O pin. If PCINT7:0 is cleared, pin change interrupt on the corresponding I/O pin is disabled. Bit 76543 210 (0x73) – PCINT30 PCINT29 PCINT28 PCINT27 PCINT26 PCINT25 PCINT24 PCMSK3 Read/Write R R/W R/W R/W R/W R/W R/W R/W Initial Value 00000 000 Bit 76543210 (0x6D) PCINT23 PCINT22 PCINT21 PCINT20 PCINT19 PCINT18 PCINT17 PCINT16 PCMSK2 Read/Write R/W R/W R/W R/W R/W R/W R/W R/W Initial Value 00000000 Bit 765432 10 (0x6C) PCINT15 PCINT14 PCINT13 PCINT12 PCINT11 PCINT10 PCINT9 PCINT8 PCMSK1 Read/Write R/W R/W R/W R/W R/W R/W R/W R/W Initial Value 000000 00 Bit 7 6 543 21 0 (0x6B) PCINT7 PCINT6 PCINT5 PCINT4 PCINT3 PCINT2 PCINT1 PCINT0 PCMSK0 Read/Write R/W R/W R/W R/W R/W R/W R/W R/W Initial Value 0 0 0 0 0 0 0 0 |
