2503N–AVR–06/08
• Bit 7:6 – COM1A1:0: Compare Output Mode for Compare unit A
• Bit 5:4 – COM1B1:0: Compare Output Mode for Compare unit B
The COM1A1:0 and COM1B1:0 control the Output Compare pins (OC1A and OC1B respec-
tively) 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 Register (DDR) bit correspond-
ing 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 depen-
dent of the WGM13:0 bits setting.
WGM13:0 bits are set to a normal or a CTC mode (non-PWM).
