Transmitter Interrupts
The transmitter generates a single interrupt when the Transmit Data Register Empty bit
(TDRE) is set to 1. This indicates that the transmitter is ready to accept new data for
transmission. The TDRE interrupt occurs after the Transmit shift register has shifted the
first bit of data out. The Transmit Data register can now be written with the next character
to send. This action provides 7 bit periods of latency to load the Transmit Data register
before the Transmit shift register completes shifting the current character. Writing to the
UART Transmit Data register clears the
Receiver Interrupts
The receiver generates an interrupt when any of the following occurs:
A data byte is received and is available in the UART Receive Data register. This interrupt
can be disabled independently of the other receiver interrupt sources. The received data in-
terrupt occurs after the receive character has been received and placed in the Receive Data
register. To avoid an overrun error, software must respond to this received data available
condition before the next character is completely received.
In MULTIPROCESSOR mode (MPEN = 1), the receive data interrupts are dependent on
Note:
the multiprocessor configuration and the most recent address byte.
A break is received
An overrun is detected
A data framing error is detected
UART Overrun Errors
When an overrun error condition occurs the UART prevents overwriting of the valid data
currently in the Receive Data register. The Break Detect and Overrun status bits are not
displayed until after the valid data has been read.
After the valid data has been read, the UART Status 0 register is updated to indicate the
overrun condition (and Break Detect, if applicable). The RDA bit is set to 1 to indicate that
the Receive Data register contains a data byte. However, because the overrun error
occurred, this byte cannot contain valid data and must be ignored. The
if the overrun was caused by a break condition on the line. After reading the status byte
indicating an overrun error, the Receive Data register must be read again to clear the error
bits is the UART Status 0 register. Updates to the Receive Data register occur only when
the next data word is received.
