Input Capture Register 1 –
ICR1H and ICR1L
Timer/Counter Interrupt Mask
Register – TIMSK
124
ATmega8515(L)
(1)
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 per-
formed using an 8-bit temporary High Byte Register (TEMP). This temporary register is
shared by all the other 16-bit registers. See “Accessing 16-bit Registers” on page 100.
Note:
• Bit 7 – TOIE1: Timer/Counter1, Overflow Interrupt Enable
When this bit is written to one, and the I-flag in the Status Register is set (interrupts glob-
ally enabled), the Timer/Counter1 overflow interrupt is enabled. The corresponding
Interrupt Vector (see “Interrupts” on page 54) is executed when the TOV1 Flag, located
in TIFR, is set.
• Bit 6 – OCIE1A: Timer/Counter1, Output Compare A Match Interrupt Enable
When this bit is written to one, and the I-flag in the Status Register is set (interrupts glob-
ally enabled), the Timer/Counter1 Output Compare A Match interrupt is enabled. The
corresponding Interrupt Vector (see “Interrupts” on page 54) is executed when the
OCF1A Flag, located in TIFR, is set.
• Bit 5 – OCIE1B: Timer/Counter1, Output Compare B Match Interrupt Enable
When this bit is written to one, and the I-flag in the Status Register is set (interrupts glob-
ally enabled), the Timer/Counter1 Output Compare B Match interrupt is enabled. The
corresponding Interrupt Vector (see “Interrupts” on page 54) is executed when the
OCF1B Flag, located in TIFR, is set.
• Bit 3 – TICIE1: Timer/Counter1, Input Capture Interrupt Enable
When this bit is written to one, and the I-flag in the Status Register is set (interrupts glob-
ally enabled), the Timer/Counter1 Input Capture interrupt is enabled. The corresponding
Interrupt Vector (see “Interrupts” on page 54) is executed when the ICF1 Flag, located in
TIFR, is set.

Timer1 bits are described in this section. The remaining bits are described in their
respective timer sections.
