• AIN0/XCK0 – Port E, Bit 2
AIN0 – Analog Comparator Positive input. This pin is directly connected to the positive input of
the Analog Comparator.
XCK0, USART0 External Clock. The Data Direction Register (DDE2) controls whether the clock
is output (DDE2 set) or input (DDE2 cleared). The XCK0 pin is active only when the USART0
operates in synchronous mode.
• PDO/TXD0 – Port E, Bit 1
PDO, SPI Serial Programming Data output. During Serial Program Downloading, this pin is used
as data output line for the ATmega64A.
TXD0, UART0 Transmit Pin.
• PDI/RXD0 – Port E, Bit 0
PDI, SPI Serial Programming Data input. During serial program downloading, this pin is used as
data input line for the ATmega64A.
RXD0, USART0 Receive pin. Receive Data (Data Input pin for the USART0). When the
USART0 Receiver is enabled this pin is configured as an input regardless of the value of
DDRE0. When the USART0 forces this pin to be an input, a logical one in PORTE0 will turn on
the internal pull-up.
