ATmega8535(L)
When OC0 is connected to the pin, the function of the COM01:0 bits depends on the
WGM01:0 bit setting. Table 40 shows the COM01:0 bit functionality when the WGM01:0
bits are set to a normal or CTC mode (non-PWM).
Table 40. Compare Output Mode, non-PWM Mode
Table 41 shows the COM01:0 bit functionality when the WGM01:0 bits are set to fast
PWM mode.
Table 41. Compare Output Mode, Fast PWM Mode
Note:
Table 42 shows the COM01:0 bit functionality when the WGM01:0 bits are set to phase
correct PWM mode.
