8-bit Timer/Counter Register Description
Timer/Counter0 Control Register A – TCCR0A
• Bit 7:6 – COM0A1:0: Compare Match Output Mode A
These bits control the Output Compare pin (OC0A) behavior. If one or both of the COM0A1:0
bits are set, the OC0A output overrides the normal port functionality of the I/O pin it is con-
nected to. However, note that the Data Direction Register (DDR) bit corresponding to OC0A
pin must be set in order to enable the output driver.
When OC0A is connected to the pin, the function of the COM0A1:0 bits depends on the
WGM01:0 bit setting.
bits are set to a normal or CTC mode (non-PWM).
