ATmega329/3290/649/6490
• XCK/AIN0/PCINT2 – Port E, Bit 2
XCK, USART0 External Clock. The Data Direction Register (DDE2) controls whether the clock is
output (DDE2 set) or input (DDE2 cleared). The XCK pin is active only when the USART0 oper-
ates in synchronous mode.
AIN0 – Analog Comparator Positive input. This pin is directly connected to the positive input of
the Analog Comparator.
PCINT2, Pin Change Interrupt Source 2: The PE2 pin can serve as an external interrupt source.
• TXD/PCINT1 – Port E, Bit 1
TXD0, UART0 Transmit pin.
PCINT1, Pin Change Interrupt Source 1: The PE1 pin can serve as an external interrupt source.
• RXD/PCINT0 – Port E, Bit 0
RXD, 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 DDE0. When the
USART0 forces this pin to be an input, a logical one in PORTE0 will turn on the internal pull-up.
PCINT0, Pin Change Interrupt Source 0: The PE0 pin can serve as an external interrupt source.
