Alternate Functions of Port B
• Bit 4 – PUD: Pull-up Disable
When this bit is written to one, the pull-ups in the I/O ports are disabled even if the DDxn and
PORTxn Registers are configured to enable the pull-ups ({DDxn, PORTxn} = 0b01). See
figuring the Pin” on page 68
The Port B pins with alternate functions are shown in
Table 11-3.
The alternate pin configuration is as follows:
• OC0A/OC1C/PCINT7, Bit 7
OC0A, Output Compare Match A 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 OC0A 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.
PCINT7, Pin Change Interrupt source 7: The PB7 pin can serve as an external interrupt source.
• PCINT6, Bit 6
PCINT6, Pin Change Interrupt source 6: The PB6 pin can serve as an external interrupt source.
• PCINT5, Bit 5
PCINT5, Pin Change Interrupt source 5: The PB5 pin can serve as an external interrupt source.
• T1/PCINT4, Bit 4
T1, Timer/Counter1 counter source.
PCINT4, Pin Change Interrupt source 4: The PB4 pin can serve as an external interrupt source.
• PDO/MISO/PCINT3 – Port B, Bit 3
