81 / 347 page 81 ATmega32(L) 2503J–AVR–10/06 When OC0 is connected to the pin, the function of the COM01:0 bits depends on the WGM01:0 bit setting. Table 39 shows the COM01:0 bit functionality when the WGM01:0 bits are set to a normal or CTC mode (non-PWM). Table 40 shows the COM01:0 bit functionality when the WGM01:0 bits are set to fast PWM mode. Note: 1. A special case occurs when OCR0 equals TOP and COM01 is set. In this case, the compare match is ignored, but the set or clear is done at BOTTOM. See “Fast PWM Mode” on page 75 for more details. Table 41 shows the COM01:0 bit functionality when the WGM01:0 bits are set to phase correct PWM mode. Note: 1. A special case occurs when OCR0 equals TOP and COM01 is set. In this case, the compare match is ignored, but the set or clear is done at TOP. See “Phase Correct PWM Mode” on page 76 for more details. Table 39.
