13.4
The communication channel provides a full-duplex asynchronous receiver and transmitter using an
operating frequency derived from the CCB clock signal.
The transmitter accepts parallel data with a write access to the transmitter holding register (UTHR). In
FIFO mode, the data is placed directly into an internal transmitter shift register, or into the transmitter
FIFO—see
by inserting the appropriate START, STOP, and optional parity bits. Finally, the registers output a

TXRDY is set after the first character is loaded into the transmitter FIFO or UTHR.
TXRDY is set when the transmitter FIFO is full.
TXRDY is cleared when there are no characters in the transmitter FIFO or UTHR.
TXRDY is cleared when there are no characters in the transmitter FIFO or UTHR. TXRDY
remains clear when the transmitter FIFO is not yet full.
RXRDY is set when there are no characters in the receiver FIFO or URBR.
RXRDY is set when the trigger level has not been reached and there has been no time out.
RXRDY is cleared when there is at least one character in the receiver FIFO or URBR.
RXRDY is cleared when the trigger level or a time-out has been reached. RXRDY remains
cleared until the receiver FIFO is empty.
