Alternate Functions of
Port E
2513K–AVR–07/09
The Port E pins with alternate functions are shown in
Table 41. Port E Pins Alternate Functions
The alternate pin configuration is as follows:
• OC1B – Port E, Bit 2
OC1B, Output Compare Match B output: The PE2 pin can serve as an external output for the
Timer/Counter1 Output Compare B. The pin has to be configured as an output (DDE0 set (one))
to serve this function. The OC1B pin is also the output pin for the PWM mode timer function.
Table 42
page
• ALE – Port E, Bit 1
ALE is the external data memory Address Latch Enable signal.
• ICP1/INT2 – Port E, Bit 0
ICP1, Input Capture Pin: The PE0 pin can act as an Input Capture pin for Timer/Counter1.
INT2, External Interrupt Source 2: The PE0 pin can serve as an external interrupt source.
