The Port E pins with alternate functions are shown in
Table 39. Port E Pins Alternate Functions
Note:
• INT7/ICP3 – Port E, Bit 7
INT7, External Interrupt Source 7: The PE7 pin can serve as an External Interrupt source.
ICP3 – Input Capture Pin3: The PE7 pin can act as an Input Capture pin for Timer/Counter3.
• INT6/T3 – Port E, Bit 6
INT6, External Interrupt Source 6: The PE6 pin can serve as an External Interrupt source.
T3, Timer/Counter3 Counter Source.
• INT5/OC3C – Port E, Bit 5
INT5, External Interrupt Source 5: The PE5 pin can serve as an External Interrupt source.
OC3C, Output Compare Match C output: The PE5 pin can serve as an external output for the
Timer/Counter3 Output Compare C. The pin has to be configured as an output (DDE5 set – one)
to serve this function. The OC3C pin is also the output pin for the PWM mode timer function.
• INT4/OC3B – Port E, Bit 4
INT4, External Interrupt Source 4: The PE4 pin can serve as an External Interrupt source.
OC3B, Output Compare Match B output: The PE4 pin can serve as an external output for the
Timer/Counter3 Output Compare B. The pin has to be configured as an output (DDE4 set – one)
to serve this function. The OC3B pin is also the output pin for the PWM mode timer function.
• AIN1/OC3A – Port E, Bit 3
AIN1 – Analog Comparator Negative input. This pin is directly connected to the negative input of
the Analog Comparator.
OC3A, Output Compare Match A output: The PE3 pin can serve as an external output for the
Timer/Counter3 Output Compare A. The pin has to be configured as an output (DDE3 set – one)
to serve this function. The OC3A pin is also the output pin for the PWM mode timer function.
