TCNT0H and TCNT0L – Timer/Counter0
OCR0AH and OCR0AL – Output Compare Register 0 A
OCR0BH and OCR0BL – Output Compare Register 0 B
The OC0A/OC0B output is changed according to its COM0x1:0 bits setting. Note that the
FOC0A/FOC0B bits are implemented as strobes. Therefore it is the value present in the
COM0x1:0 bits that determine the effect of the forced compare.
A FOC0A/FOC0B strobe will not generate any interrupt nor will it clear the timer in Clear Timer
on Compare match (CTC) mode using OCR0A as TOP.
The FOC0A/FOC0B bits are always read as zero.
• Bits 5:0 – 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.
The two Timer/Counter I/O locations (TCNT0H and TCNT0L, combined TCNT0) 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 temporary high byte register
(TEMP). This temporary register is shared by all the other 16-bit registers. See
Registers” on page
Modifying the counter (TCNT0) while the counter is running introduces a risk of missing a com-
pare match between TCNT0 and one of the OCR0x Registers.
Writing to the TCNT0 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 (TCNT0). A match can be used to generate an Output Compare interrupt, or to
generate a waveform output on the OC0x 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
