Alternate Functions of
Port A
Alternate Functions of
Port B
2543L–AVR–08/10
• Bit 7 – 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 47
The Port A pins with alternate functions are as shown in
Table 24. Port A Pins Alternate Functions
The Port B pins with alternate functions are shown in
Table 25. Port B Pins Alternate Functions
The alternate pin configuration is as follows:
• USCK/SCL/PCINT7 - Port B, Bit 7
USCK: Three-wire mode Universal Serial Interface Clock.
SCL: Two-wire mode Serial Clock for USI Two-wire mode.
PCINT7: Pin Change Interrupt source 7. The PB7 pin can serve as an external interrupt source.
• DO/PCINT6 - Port B, Bit 6
DO: Three-wire mode Universal Serial Interface Data output. Three-wire mode Data output over-
rides PORTB6 value and it is driven to the port when data direction bit DDB6 is set (one).
However the PORTB6 bit still controls the pull-up enabling pull-up, if direction is input and
PORTB6 is set (one).
PCINT6: Pin Change Interrupt Source 6. The PB6 pin can serve as an external interrupt source.
