Alternate Functions of
Port D
56
ATtiny2313
The Port D pins with alternate functions are shown in
Table 28. 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
• OC0B/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 (DDD5 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).
• T0 – Port D, Bit 4
T0: Timer/Counter0 External Counter Clock input is enabled by setting (one) the bits CS02 and
CS01 in the Timer/Counter0 Control Register (TCCR0).
• INT1 – Port D, Bit 3
INT1: External Interrupt Source 1. The PD3 pin can serve as an external interrupt source to the
MCU.
• INT0/XCK/CKOUT – Port D, Bit 2
INT0: External Interrupt Source 0. The PD2 pin can serve as en external interrupt source to the
MCU.
XCK: USART Transfer Clock used only by Synchronous Transfer mode.
CKOUT: System Clock Output
• TXD – Port D, Bit 1
TXD: UART Data Transmitter.
• RXD – Port D, Bit 0
RXD: UART Data Receiver.
