When OC0 is connected to the pin, the function of the COM01:0 bits depends on the
WGM01:0 bit setting. Table 45 shows the COM01:0 bit functionality when the WGM01:0
bits are set to a normal or CTC mode (non-PWM).
Table 45. Compare Output Mode, non-PWM Mode
Table 46 shows the COM01:0 bit functionality when the WGM01:0 bits are set to fast
PWM mode.
Table 46. Compare Output Mode, Fast PWM Mode
Note:
Table 47 shows the COM01:0 bit functionality when the WGM01:0 bits are set to phase
correct PWM mode.
