ATmega162(V/U/L)
• Bit 5:4 – COM21:0: Compare Match Output Mode
These bits control the Output Compare pin (OC2) behavior. If one or both of the
COM21:0 bits are set, the OC2 output overrides the normal port functionality of the I/O
pin it is connected to. However, note that the Data Direction Register (DDR) bit corre-
sponding to OC2 pin must be set in order to enable the output driver.
When OC2 is connected to the pin, the function of the COM21:0 bits depends on the
WGM21:0 bit setting. Table 61 shows the COM21:0 bit functionality when the WGM21:0
bits are set to a normal or CTC mode (non-PWM).
Table 61. Compare Output Mode, non-PWM Mode
Table 62 shows the COM21:0 bit functionality when the WGM21:0 bits are set to fast
PWM mode.
Table 62. Compare Output Mode, Fast PWM Mode
Note:
Table 63 shows the COM21:0 bit functionality when the WGM21:0 bits are set to phase
correct PWM mode.
