ATtiny25/45/85
PCMSK – Pin Change Mask Register
• Bit 5 – PCIF: Pin Change Interrupt Flag
When a logic change on any PCINT[5:0] pin triggers an interrupt request, PCIF becomes set
(one). If the I-bit in SREG and the PCIE bit in GIMSK are set (one), the MCU will jump to the cor-
responding 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.
• Bits 7:6 – Res: Reserved Bits
These bits are reserved bits in the ATtiny25/45/85 and will always read as zero.
• Bits 5:0 – PCINT[5:0]: Pin Change Enable Mask 5:0
Each PCINT[5:0] bit selects whether pin change interrupt is enabled on the corresponding I/O
pin. If PCINT[5:0] is set and the PCIE bit in GIMSK is set, pin change interrupt is enabled on the
corresponding I/O pin. If PCINT[5:0] is cleared, pin change interrupt on the corresponding I/O
pin is disabled.
