PRELIMINARY—SUBJECT TO CHANGE WITHOUT NOTICE
Installation and Setup
2.2.4 Selecting Terminal Baud Rate
The serial channel UART0 of the MCF5282 is used for serial communication and has a built in
timer. This timer is used by the dBUG ROM monitor to generate the baud rate used to communicate
with a serial terminal. A number of baud rates can be programmed. On power-up or manual
RESET, the dBUG ROM monitor firmware configures the channel for 19200 baud. Once the
dBUG ROM monitor is running, a SET command may be issued to select any baud rate supported
by the ROM monitor.
2.2.5 The Terminal Character Format
The character format of the communication channel is fixed at power-up or RESET. The default
character format is 8 bits per character, no parity and one stop bit with no flow control. It is
necessary to ensure that the terminal or PC is set to this format.
2.2.6 Connecting the Terminal
The board is now ready to be connected to a PC/terminal. Use the RS-232 serial cable to connect
the PC/terminal to the M5282EVB PCB. The cable has a 9-pin female D-sub terminal connector
at one end and a 9-pin male D-sub connector at the other end. Connect the 9-pin male connector to
connector P3 on the M5282EVB board. Connect the 9-pin female connector to one of the available
serial communication channels normally referred to as COM1 (COM2, etc.) on the PC running
terminal emulation software. The connector on the PC/terminal may be either male 25-pin or 9-pin.
It may be necessary to obtain a 25pin-to-9pin adapter to make this connection. If an adapter is
required, refer to Figure 2-2., “Pin assignment for female (Terminal) connector”.
2.2.7 Using a Personal Computer as a Terminal
A personal computer may be used as a terminal provided a terminal emulation software package is
available. Examples of this software are PROCOMM, KERMIT, QMODEM, Windows
95/98/2000/XP Hyper Terminal or similar packages. The board should then be connected as
described in section 2.2.6, “Connecting the Terminal.”
Once the connection to the PC is made, power may be applied to the PC and the terminal emulation
software can be run. In terminal mode, it is necessary to select the baud rate and character format
for the channel. Most terminal emulation software packages provide a command known as "Alt-p"
(press the p key while pressing the Alt key) to choose the baud rate and character format. The
character format should be 8 bits, no parity, one stop bit. (see section 1.9.5 The Terminal Character
Format.) The baud rate should be set to 19200. Power can now be applied to the board.
