briefly describes the UART module signals.
shows a signal configuration for a UART/RS-232 interface.
UART registers are accessible only as bytes.
Interrupt can mean an interrupt request asserted to the CPU or a DMA
request.
Transmitter Serial Data Output. UTXDn is held high (mark condition) when the transmitter is
disabled, idle, or operating in the local loopback mode. Data is shifted out on UTXDn on the
falling edge of the clock source, with the least significant bit (lsb) sent first.
Receiver Serial Data Input. Data received on URXDn is sampled on the rising edge of the clock
source, with the lsb received first.
Clear-to- Send. This input can generate an interrupt on a change of state.
Request-to-Send. This output can be programmed to be negated or asserted automatically by
the receiver or the transmitter. When connected to a transmitter’s UCTSn, URTSn can control
serial data flow.
