3.3 V/5.0 V Dual Universal Asynchronous Receiver/Transmitter
Description
Interrupt request: Active LOW, open-drain, output which signals the
CPU that one or more of the eight maskable interrupting conditions
are true. This pin requires a pull-up.
Crystal 1: Crystal or external clock input. A crystal or clock of the
specified limits must be supplied at all times. When a crystal is used, a
capacitor must be connected from this pin to ground (see
Crystal 2: Connection for other side of the crystal. When a crystal is
used, a capacitor must be connected from this pin to ground (see
Figure
be left open.
Channel A receiver serial data input: The least significant bit is
received first. See note on drive levels at block diagram
Channel B receiver serial data input: The least significant bit is
received first. See note on drive levels at block diagram
Channel A transmitter serial data output: The least significant bit is
transmitted first. This output is held in the ‘mark condition when the
transmitter is disabled, idle or when operating in local loopback mode.
See note on drive levels at block diagram
Channel B transmitter serial data output: The least significant bit is
transmitted first. This output is held in the Mark condition when the
transmitter is disabled, idle, or when operating in local loopback mode.
See note on drive levels at block diagram
Output 0: General purpose output or channel A request to send
(RTSAN, active LOW). Can be deactivated automatically on receive or
transmit.
Output 1: General purpose output or channel B request to send
(RTSBN, active LOW). Can be deactivated automatically on receive or
transmit.
Output 2: General purpose output, or channel A transmitter 1 or 16
clock output, or channel A receiver 1 clock output.
Output 3: General purpose output or open-drain, active LOW
counter/timer output or channel B transmitter 1 clock output, or
channel B receiver 1 clock output.
Output 4: General purpose output or channel A open-drain, active
LOW, RxA interrupt ISR [1] output.
Output 5: General purpose output or channel B open-drain, active
LOW, RxB interrupt ISR[5] output.
Output 6: General purpose output or channel A open-drain, active
LOW, TxA interrupt ISR[0] output.
Output 7: General purpose output, or channel B open-drain, active
LOW, TxB interrupt ISR[4] output.
Input 0: General purpose input or channel A clear to send active LOW
input (CTSAN).
Input 1: General purpose input or channel B clear to send active LOW
input (CTSBN).
Input 2: General purpose input or counter/timer external clock input.
