Atmel ATA6616/ATA6617
Input Capture Register – ICR1H and ICR1L
Timer/Counter1 Interrupt Mask Register – TIMSK1
The Output Compare Registers are 16-bit in size. To ensure that both the high and low bytes
are written simultaneously when the CPU writes to 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.
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.
• Bit 7..6 – 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
ICF1 flag, located in TIFR1, is set.
• Bit 4..3 – 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
when 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
when the OCF1A flag, located in TIFR1, is set.
