Alternate Functions of Port B
The Port B pins with alternate functions are shown in
Table 13-6.
The alternate pin configuration is as follows:
• OC0B/PCINT15 – Port B, Bit 7
OC0B, Output Compare Match B output: The PB7 pin can serve as an external output for the
Timer/Counter0 Output Compare. The pin has to be configured as an output (DDB7 set (one)) to
serve this function. The OC0B pin is also the output pin for the PWM mode timer function.
PCINT15, Pin Change Interrupt Source 15. The PB7 pin can serve as external interrupt source
to the MCU.
• OC0A/PCINT14 – Port B, Bit 6
OC0A, Output Compare Match A output: The PB6 pin can serve as an external output for the
Timer/Counter0 Output Compare. The pin has to be configured as an output (DDB6 set (one)) to
serve this function. The OC0A pin is also the output pin for the PWM mode timer function.
PCINT14, Pin Change Interrupt Source 14. The PB6 pin can serve as external interrupt source
to the MCU.
• PCINT13:12 – Port B, Bit 5:4
PCINT13 - PCINT12, Pin Change Interrupt Source 13:12. The PB5:4 pinS can serve as external
interrupt sources to the MCU.
• TCK/PCINT11 – Port B, Bit 3
TCK, JTAG Test Clock: JTAG operation is synchronous to TCK. When the JTAG Interface is
enabled, this pin can not be used as an I/O pin.
PCINT11, Pin Change Interrupt Source 11. The PB3 pin can serve as external interrupt source
to the MCU.
