• 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 (OC1Ai and OC1Bi respec-
tively) behavior. If one or both of the COM1A1:0 bits are written to one, the OC1Ai 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 OC1Bi output overrides the normal port functionality of
the I/O pin it is connected to. However, note that the Data Direction Register (DDR) bit and
OC1xi bit (TCCR1D) corresponding to the OC1Ai or OC1Bi pin must be set in order to enable
the output driver.
When the OC1Ai or OC1Bi is connected to the pin, the function of the COM1A/B1:0 bits is
dependent of the WGM13:0 bits setting.
when the WGM13:0 bits are set to a Normal or a CTC mode (non-PWM).
