ATmega16HVB/32HVB

• Bit 7:0 – PCINT11:4: Pin Change Enable Mask 15..8

These bits select whether pin change interrupt is enabled on the corresponding I/O pin. If

PCINT11:4 is set and the PCIE1 bit in EIMSK is set, pin change interrupt is enabled on the cor-

responding I/O pin. If PCINT11:4 is cleared, pin change interrupt on the corresponding I/O pin is

disabled.

13.2.7

PCMSK0 – Pin Change Mask Register 0

• Bits 7:4 – RES: Reserved Bits

These bits are reserved bits ins the ATmega16HVB/32HVB, and will always read as zero.

• Bit 3:0 – PCINT3:0: Pin Change Enable Mask 3:0

Each PCINT3:0 bit selects whether pin change interrupt is enabled on the corresponding I/O pin.

If PCINT3:0 is set and the PCIE0 bit in PCICR is set, pin change interrupt is enabled on the cor-

responding I/O pin. If PCINT3:0 is cleared, pin change interrupt on the corresponding I/O pin is

disabled.
