Table 49. Waveform Generation Mode Bit Description
Note:
• Bit 5:4 – COM0A1:0: Compare Match Output Mode
These bits control the Output Compare pin (OC0A) behavior. If one or both of the
COM0A1:0 bits are set, the OC0A output overrides the normal port functionality of the
I/O pin it is connected to. However, note that the Data Direction Register (DDR) bit cor-
responding to the OC0A pin must be set in order to enable the output driver.
When OC0A is connected to the pin, the function of the COM0A1:0 bits depends on the
WGM01:0 bit setting. Table 50 shows the COM0A1:0 bit functionality when the
WGM01:0 bits are set to a normal or CTC mode (non-PWM).
Table 50. Compare Output Mode, non-PWM Mode
Table 51 shows the COM0A1:0 bit functionality when the WGM01:0 bits are set to fast
PWM mode.
