ICR1H and ICR1L – Input Capture Register
TIMSK1 – Timer/Counter1 Interrupt Mask Register
The Input Capture is updated with the counter (TCNT1) value each time an event occurs on
the ICP1 pin (or optionally on the Analog Comparator output for Timer/Counter1). 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 – Res: Reserved Bits
These bits are reserved for future use.
• Bit 5 – ICIE1: 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/Counter1 Input Capture interrupt is enabled. The corresponding Interrupt
Vector
located in TIFR1, is set.
• Bits 4:3 – Res: Reserved Bits
These bits are reserved for future use.
• Bit 2 – OCIE1B: 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/Counter1 Output Compare B Match interrupt is enabled. The correspond-
ing Interrupt Vector
the OCF1B flag, located in TIFR1, is set.
• Bit 1 – OCIE1A: 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/Counter1 Output Compare A Match interrupt is enabled. The correspond-
ing Interrupt Vector
the OCF1A flag, located in TIFR1, is set.
• Bit 0 – TOIE1: Timer/Counter 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/Counter1 Overflow interrupt is enabled. The corresponding Interrupt Vec-
tor
located in TIFR1, is set.
