60 / 317 page  60 ATmega32(L) 2503F–AVR–12/03 Note: 1. When enabled, the Two-wire Serial Interface enables slew-rate controls on the output pins PC0 and PC1. This is not shown in the figure. In addition, spike filters are con- nected between the AIO outputs shown in the port figure and the digital logic of the TWI module. Alternate Functions of Port D The Port D pins with alternate functions are shown in Table 31. The alternate pin configuration is as follows: • OC2 – Port D, Bit 7 OC2, Timer/Counter2 Output Compare Match output: The PD7 pin can serve as an external output for the Timer/Counter2 Output Compare. The pin has to be configured as an output (DDD7 set (one)) to serve this function. The OC2 pin is also the output pin for the PWM mode timer function. • ICP – Port D, Bit 6 IC P – I nput Capture Pin: The PD6 pin can ac t as an In pu t Captur e pin for Timer/Counter1. Table 30.
