Alternate Functions of Port E
The Port E pins with alternate functions are shown in
Table 13-15. Port E Pins Alternate Functions
• PCINT7 – Port E, Bit 7
PCINT7, Pin Change Interrupt Source 7: The PE7 pin can serve as an external interrupt source.
CLKO, Divided System Clock: The divided system clock can be output on the PE7 pin. The
divided system clock will be output if the CKOUT Fuse is programmed, regardless of the
PORTE7 and DDE7 settings. It will also be output during reset.
• DO/PCINT6 – Port E, Bit 6
DO, Universal Serial Interface Data output.
PCINT6, Pin Change Interrupt Source 6: The PE6 pin can serve as an external interrupt source.
• DI/SDA/PCINT5 – Port E, Bit 5
DI, Universal Serial Interface Data input.
SDA, Two-wire Serial Interface Data:
PCINT5, Pin Change Interrupt Source 5: The PE5 pin can serve as an external interrupt source.
• USCK/SCL/PCINT4 – Port E, Bit 4
USCK, Universal Serial Interface Clock.
SCL, Two-wire Serial Interface Clock.
PCINT4, Pin Change Interrupt Source 4: The PE4 pin can serve as an external interrupt source.
• AIN1/PCINT3 – Port E, Bit 3
AIN1 – Analog Comparator Negative input. This pin is directly connected to the negative input of
the Analog Comparator.
PCINT3, Pin Change Interrupt Source 3: The PE3 pin can serve as an external interrupt source.
