Serial Communication Controllers (SCCs)
command, or after a transmitter error (underrun or CTS lost). The transparent controller will
resume transmission from the current TBPTR in the channel’s Tx BD table.
INIT TX PARAMETERS Command. This command initializes all transmit parameters in this
serial channel’s parameter RAM to their reset state. This command should only be issued
when the transmitter is disabled. Note that the INIT TX AND RX PARAMETERS command
may also be used to reset both transmit and receive parameters.
7.10.21.6.2 Receive Commands. The following paragraphs describe the transparent
receive commands.
ENTER HUNT MODE Command . After a hardware or software reset and the enabling of the
channel in the SCC mode register, the channel is in the receive enable mode and will use
the first BD in the table.
The ENTER HUNT MODE command is used to force the transparent receiver to abort
reception of the current frame and enter the hunt mode. In the hunt mode, the transparent
controller waits for the synchronization sequence. After receiving the command, the current
receive buffer is closed. Further data reception will use the next BD.
CLOSE Rx BD Command . The CLOSE Rx BD command is used to force the SCC to close
the Rx BD, if it is currently being used, and to use the next BD for any subsequent data that
is received. If the SCC is not in the process of receiving data, no action is taken by this com-
mand.
INIT RX PARAMETERS Command . This command initializes all the receive parameters in
this serial channel’s parameter RAM to their reset state. This command should only be
issued when the receiver is disabled. Note that the INIT TX AND RX PARAMETERS com-
mand may also be used to reset both receive and transmit parameters.
7.10.21.7 TRANSPARENT ERROR-HANDLING PROCEDURE. The SCC reports mes-
sage reception and transmission error conditions using the channel BDs, the error counters,
and the SCC event register.
7.10.21.7.1 Transmission Errors. The following paragraphs describe various types of
transmission errors.
Transmitter Underrun . When this error occurs, the channel terminates buffer transmission,
closes the buffer, sets the UN bit in the BD, and generates the TXE interrupt (if enabled).
The channel resumes transmission after the reception of the RESTART TRANSMIT com-
mand. Underrun can occur after a transmit frame for which the L-bit in the Tx BD was not
set. In this case, only the TXE bit is set. Underrun cannot occur between transparent frames.
CTS Lost During Message Transmission . When this error occurs, the channel terminates
buffer transmission, closes the buffer, sets the CT bit in the BD, and generates the TXE
interrupt if it is enabled. The channel will resume transmission after the reception of the
RESTART TRANSMIT command.
