TCCR1A – Timer/Counter Control Register A
Bits 7:6 – COMnA[1:0]: Compare Match Output A Mode
These bits control the Output Compare pin (OCnA) behavior. If one or both of the COMnA[1:0]
bits are set, the OCnA 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 OCnA pin
must be set in order to enable the output driver.
When OCnA is connected to the pin, the function of the COMnA[1:0] bits depends on the
WGMn[2:0] bit setting. Table 12-2 on page 92 shows the COMnA[1:0] bit functionality when the
WGMn[2:0] bits are set to a normal or CTC mode (non-PWM).
Table 12-3 on page 92 shows the COMnA[1:0] bit functionality when the WGMn[1:0] bits are set
to fast 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 “Fast PWM Mode” on page 86
for more details.
