Timer/Counter1 Control Register D – TCCR1D
Timer/Counter1 – TCNT1H and TCNT1L
Output Compare Register A – OCR1AH and OCR1AL
Output Compare Register B – OCR1BH and OCR1BL
• Bit 7:4 – OC1Bi: Output Compare Pin Enable for Channel B
The OC1Bi bits enable the Output Compare pins of Channel B as shown in
page
• Bit 3:0 – OC1Ai: Output Compare Pin Enable for Channel A
The OC1Ai bits enable the Output Compare pins of Channel A as shown in
page
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 temporary high byte register
(TEMP). This temporary register is shared by all the other 16-bit registers.
16-bit Registers” on page 136.
Modifying the counter (TCNT1) while the counter is running introduces a risk of missing a
compare match between TCNT1 and one of the OCR1A/B 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 OC1A/B pin.
