Alternate Functions of Port B
2514P–AVR–07/06
Table 29. Overriding Signals for Alternate Functions in PA3..PA0
The Port B pins with alternate functions are shown in Table 30.
Table 30. Port B Pins Alternate Functions
The alternate pin configuration is as follows:
• OC2A/PCINT15, Bit 7
OC2, Output Compare Match A output: The PB7 pin can serve as an external output for
the Timer/Counter2 Output Compare A. The pin has to be configured as an output
(DDB7 set (one)) to serve this function. The OC2A pin is also the output pin for the PWM
mode timer function.
PCINT15, Pin Change Interrupt source 15: The PB7 pin can serve as an external inter-
rupt source.
