ICR0H and ICR0L – Input Capture Register 0
TIMSK0 – Timer/Counter Interrupt Mask Register 0
8-bit temporary high byte register (TEMP). This temporary register is shared by all the other 16-
bit registers. See
The Input Capture is updated with the counter (TCNT0) value each time an event occurs on the
ICP0 pin (or optionally on the Analog Comparator output for Timer/Counter0). The Input Capture
can be used for defining the counter TOP value.
The Input Capture Register is 16-bit in size. To ensure that both the high and low bytes are read
simultaneously when the CPU accesses these registers, the access is performed using an 8-bit
temporary high byte register (TEMP). This temporary register is shared by all the other 16-bit
registers.
• Bits 7:6, 4:3 – Reserved Bits
These bits are reserved for future use. For ensuring compatibility with future devices, these bits
must be written to zero when the register is written.
• Bit 5 – ICIE0: Timer/Counter0, Input Capture Interrupt Enable
When this bit is written to one, and the I-flag in the Status Register is set (interrupts globally
enabled), the Timer/Counter0 Input Capture interrupt is enabled. The
corresponding Interrupt Vector (See “Interrupts” on page 66.) is executed when the
ICF0 Flag, located in TIFR0, is set.
• Bit 2 – OCIE0B: Timer/Counter0, Output Compare B Match Interrupt Enable
When this bit is written to one, and the I-flag in the Status Register is set (interrupts globally
enabled), the Timer/Counter0 Output Compare B Match interrupt is enabled. The corresponding
Interrupt Vector (see
TIFR0, is set.
• Bit 1 – OCIE0A: Timer/Counter0, Output Compare A Match Interrupt Enable
When this bit is written to one, and the I-flag in the Status Register is set (interrupts globally
enabled), the Timer/Counter0 Output Compare A Match interrupt is enabled. The corresponding
Interrupt Vector (see
TIFR0, is set.
• Bit 0 – TOIE0: Timer/Counter0, Overflow Interrupt Enable
When this bit is written to one, and the I-flag in the Status Register is set (interrupts globally
enabled), the Timer/Counter0 Overflow interrupt is enabled. The corresponding Interrupt Vector
