16-bit Timer/Counter
Register Description
Timer/Counter1 Control
Register A – TCCR1A
2512K–AVR–01/10
• Bit 7:6 – COM1A1:0: Compare Output Mode for Channel A
• Bit 5:4 – COM1B1:0: Compare Output Mode for Channel B
The COM1A1:0 and COM1B1:0 control the Output Compare pins (OC1A and OC1B
respectively) behavior. If one or both of the COM1A1:0 bits are written to one, the OC1A
output overrides the normal port functionality of the I/O pin it is connected to. If one or
both of the COM1B1:0 bit are written to one, the OC1B output overrides the normal port
functionality of the I/O pin it is connected to. However, note that the Data Direction Reg-
ister (DDR) bit corresponding to the OC1A or OC1B pin must be set in order to enable
the output driver.
When the OC1A or OC1B is connected to the pin, the function of the COM1x1:0 bits is
dependent of the WGM13:0 bits setting. Table 50 shows the COM1x1:0 bit functionality
when the WGM13:0 bits are set to a normal or a CTC mode (non-PWM).
Table 50. Compare Output Mode, non-PWM
Table 51 shows the COM1x1:0 bit functionality when the WGM13:0 bits are set to the
fast PWM mode.
Table 51. Compare Output Mode, Fast PWM
Note:
Table 52 shows the COM1x1:0 bit functionality when the WGM13:0 bits are set to the
phase correct or the phase and frequency correct, PWM mode.

1. A special case occurs when OCR1A/OCR1B equals TOP and COM1A1/COM1B1 is
set. In this case the Compare Match is ignored, but the set or clear is done at TOP.
See “Fast PWM Mode” on page 111. for more details.
