Timer/Counter1 – TCNT1H
and TCNT1L
Output Compare Register 1 A
– OCR1AH and OCR1AL
Output Compare Register 1 B
– OCR1BH and OCR1BL
2514P–AVR–07/06
A FOC1A/FOC1B strobe will not generate any interrupt nor will it clear the timer in Clear
Timer on Compare match (CTC) mode using OCR1A as TOP.
The FOC1A/FOC1B bits are always read as zero.
The two Timer/Counter I/O locations (TCNT1H and TCNT1L, combined TCNT1) give
direct access, both for read and for write operations, to the Timer/Counter unit 16-bit
counter. To ensure that both the high and low bytes are read and written simultaneously
when the CPU accesses these registers, the access is performed using an 8-bit tempo-
rary High Byte Register (TEMP). This temporary register is shared by all the other 16-bit
registers. See “Accessing 16-bit Registers” on page 98.
Modifying the counter (TCNT1) while the counter is running introduces a risk of missing
a compare match between TCNT1 and one of the OCR1x Registers.
Writing to the TCNT1 Register blocks (removes) the compare match on the following
timer clock for all compare units.
The Output Compare Registers contain a 16-bit value that is continuously compared
with the counter value (TCNT1). A match can be used to generate an Output Compare
interrupt, or to generate a waveform output on the OC1x pin.
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. See “Accessing 16-bit Registers” on page 98.
