to phase correct PWM mode.
Table 13-4.
Note:
• Bits 5:4 – COM0B1:0: Compare Match Output B Mode
These bits control the Output Compare pin (OC0B) behavior. If one or both of the COM0B1:0
bits are set, the OC0B 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 the
OC0B pin must be set in order to enable the output driver.
When OC0B is connected to the pin, the function of the COM0B1:0 bits depends on the
WGM02:0 bit setting.
WGM02:0 bits are set to a normal or CTC mode (non-PWM).
