Alternate Functions of
Port B
2490Q–AVR–06/10
Table 29. Overriding Signals for Alternate Functions in PA3..PA0
Note:
The Port B pins with alternate functions are shown in
Table 30. Port B Pins Alternate Functions
Note:
The alternate pin configuration is as follows:
• OC2/OC1C, Bit 7
OC2, Output Compare Match output: The PB7 pin can serve as an external output for the
Timer/Counter2 Output Compare. The pin has to be configured as an output (DDB7 set (one)) to
serve this function. The OC2 pin is also the output pin for the PWM mode timer function.
OC1C, Output Compare Match C output: The PB7 pin can serve as an external output for the
Timer/Counter1 Output Compare C. The pin has to be configured as an output (DDB7 set (one))
to serve this function. The OC1C pin is also the output pin for the PWM mode timer function.
