Note: 1. IC3, T3, OC3C, OC3B, OC3B, OC3A, and XCK0 not applicable in ATmega103 com-

patibility mode.

• INT7/IC3 – Port E, Bit 7

INT7, External Interrupt Source 7: The PE7 pin can serve as an External Interrupt

source.

IC3 – 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.
