Note:
• Bits 5:4 – COM0B[1:0] : Compare Match Output B Mode
These bits control the Output Compare pin (OC0B) behavior. If one or both of COM0B[1:0] bits
are set, the OC0B output overrides the normal port functionality of the I/O pin it is connected to.
The Data Direction Register (DDR) bit corresponding to the OC0B pin must be set in order to
enable the output driver.
When OC0B is connected to the pin, the function of COM0B[1:0] bits depend on WGM0[2:0] bit
setting.
