4317B–AVR–02/05

OC1B, Output Compare Match B output: This pin can serve as an external output for the

Timer/Counter1 Output Compare B. The pin has to be configured as an output (DDC1

set “one”) to serve this function. This pin is also the output pin for the PWM mode timer

function.

• PSCOUT10/INT3 – Bit 0

PSCOUT10: Output 0 of PSC 1.

INT3, External Interrupt source 3: This pin can serve as an external interrupt source to

the MCU.

Table 28 and Table 29 relate the alternate functions of Port C to the overriding signals

shown in Figure 28 on page 68.
