        Port D as General Digital I/O
        PDn, General I/O pin: The DDDn bit in the DDRD Register selects the direction of this
        pin. If DDDn is set (one), PDn is configured as an output pin. If DDDn is cleared (zero),
        PDn is configured as an input pin. If PDn is set (one) when configured as an input pin,
        the MOS pull-up resistor is activated. To switch the pull-up resistor off, the PDn has to
        be cleared (zero) or the pin has to be configured as an output pin.The port pins are tri-
        stated when a reset condition becomes active, even if the clock is not running.
        Note:
        1. n: 7,6..0, pin number.
        Alternate Functions of Port D
        AIN1 – Port D, Bit 7
        AIN1, Analog Comparator Negative Input. When configured as an input (DDD7 is
        cleared [zero]), and with the internal MOS pull-up resistor switched off (PD7 is cleared
        [zero]), this pin also serves as the negative input of the On-chip Analog Comparator.
        During Power-down mode, the Schmitt trigger of the digital input is disconnected. This
        allows analog signals, which are close to V
        CC/2, to be present during Power-down with-
        out causing excessive power consumption.
        AIN0 – Port D, Bit 6
        AIN0, Analog Comparator Positive Input. When configured as an input (DDD6 is cleared
        [zero]), and with the internal MOS pull-up resistor switched off (PD6 is cleared [zero]),
        this pin also serves as the positive input of the On-chip Analog Comparator. During
        Power-down mode, the Schmitt trigger of the digital input is disconnected. This allows
        analog signals, which are close to V
        CC/2, to be present during Power-down without
        causing excessive power consumption.
        T1 – Port D, Bit 5
        T1, Timer/Counter1 Counter Source. See the Timer description for further details
        T0 – Port D, Bit 4
        T0: Timer/Counter0 Counter Source. See the Timer description for further details.
        INT1 – Port D, Bit 3
        INT1, External Interrupt Source 1: The PD3 pin can serve as an external interrupt
        source to the MCU. See the interrupt description for further details and how to enable
        the source.
        INT0 – Port D, Bit 2
        INT0, External Interrupt Source 0: The PD2 pin can serve as an external interrupt
        source to the MCU. See the interrupt description for further details and how to enable
        the source.
