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.
11.11.4
TCNT0H and TCNT0L – Timer/Counter0
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
Modifying the counter (TCNT0) while the counter is running introduces a risk of missing a compare 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.
11.11.5
OCR0AH and OCR0AL – Output Compare Register 0 A
11.11.6
OCR0BH and OCR0BL – Output Compare Register 0 B
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 simultane-
ously 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
