• XCK/AIN0/PCINT2 – Port E, Bit 2
XCK, USART 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
USART operates 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, USART Receive pin. Receive Data (Data input pin for the USART). When the
USART Receiver is enabled this pin is configured as an input regardless of the value of
DDE0. When the USART 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.
Table 40 and Table 41 relates the alternate functions of Port E to the overriding signals
shown in Figure 26 on page 60.
