Table 12-4 on page 93 shows the COMnA[1:0] bit functionality when the WGMn[2:0] bits are set
to phase correct PWM mode.
Note:
1. A special case occurs when OCRnA equals TOP and COMnA1 is set. In this case, the Com-
pare Match is ignored, but the set or clear is done at TOP. See “Phase Correct PWM Mode” on
page 88 for more details.
Bits 5:4 – COMnB[1:0]: Compare Match Output B Mode
These bits control the Output Compare pin (OCnB) behavior. If one or both of the COMnB[1:0]
bits are set, the OCnB output overrides the normal port functionality of the I/O pin it is connected
to. However, note that the Data Direction Register (DDR) bit corresponding to the OCnB pin
must be set in order to enable the output driver.
When OCnB is connected to the pin, the function of the COMnB[1:0] bits depends on the
WGMn[2:0] bit setting. Table 12-5 on page 93 shows the COMnB[1:0] bit functionality when the
WGMn[2:0] bits are set to a normal or CTC mode (non-PWM).
Table 12-6 on page 93 shows the COMnB[1:0] bit functionality when the WGMn[2:0] bits are set
to fast PWM mode.
Note:
1. A special case occurs when OCRnB equals TOP and COMnB1 is set. In this case, the Com-
pare Match is ignored, but the set or clear is done at TOP. See “Fast PWM Mode” on page 86
for more details.
