3.3 V/5.0 V Dual Universal Asynchronous Receiver/Transmitter
Description
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.
Input 3: General purpose input or channel A transmitter external clock
input (TxCA). When the external clock is used by the transmitter, the
transmitted data is clocked on the falling edge of the clock.
Input 4: General purpose input or channel A receiver external clock
input (RxCA). When the external clock is used by the receiver, the
received data is sampled on the rising edge of the clock.
Input 5: General purpose input or channel B transmitter external clock
input (TxCB). When the external clock is used by the transmitter, the
transmitted data is clocked on the falling edge of the clock.
Input 6: General purpose input or channel B receiver external clock
input (RxCB). When the external clock is used by the receiver, the
received data is sampled on the rising edge of the clock.
Power Supply: 3.3 V
