Alternate Functions of Port D
56
ATtiny2313/V
Table 28. Overriding Signals for Alternate Functions in PB3..PB0
The Port D pins with alternate functions are shown in Table 29.
Table 29. Port D Pins Alternate Functions
The alternate pin configuration is as follows:
• ICP – Port D, Bit 6
ICP: Timer/Counter1 Input Capture Pin. The PD6 pin can act as an Input Capture pin for
Timer/Counter1
• OC1B/T1 – Port D, Bit 5
OC0B: Output Compare Match B output: The PD5 pin can serve as an external output
for the Timer/Counter0 Output Compare B. The pin has to be configured as an output
(DDB5 set (one)) to serve this function. The OC0B pin is also the output pin for the PWM
mode timer function.
T1: Timer/Counter1 External Counter Clock input is enabled by setting (one) the bits
CS02 and CS01 in the Timer/Counter1 Control Register (TCCR1).
