• PSCIN1/OC1B, Bit 1
PCSIN1, PSC 1 Digital Input.
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 11-7 and Table 11-8 relate the alternate functions of Port C to the overriding signals
shown in Figure 11-5 on page 67.
