Freescale Semiconductor MMDS0508 manual Introduction to the Bus Analyzer, Baudrate, Showprot

Freescale Semiconductor, Inc.

MMDS Target Component

4.10 Bus Analyzer

For a PC: Any valid communication device (COM1,COM2,etc.).

Example:COMDEV=COM2

For SUN:Any valid communication device (/dev/ttya, etc.).

Example:comdev=/dev/ttyb

4.9.1.2 BAUDRATE

This parameter specifies the communication baud rate between the host computer and the target system. The debugger default is 9600 baud, but you may set any of these baud rates:

1200, 2400, 4800, 9600, 19200, 28800, 38400, 57600, 115200.

Example:BAUDRAUTE=19200

4.9.1.3 SHOWPROT

This parameter specifies whether to report commands and responses in the command line window. To have the system report the commands and responses, give this parameter the value 1. To have the system not do this reporting, give this parameter the value 0. (Another way to specify reporting is checking the Show Protocol checkbox of the Communication Device Specification dialog box.)

Please see the section Communication Configuration, Communication Device Specification.

4.10 Bus Analyzer

4.10.1 Introduction to the Bus Analyzer

Except for emulating the target-system MCU, the most important feature that a microcontroller development tool can offer is analyzing program execution activities on the target MCU bus. This analysis lets you determine what is occurring in a system, without actually affecting the system.

NOTE	The MMDS0508 bus analyzer shows the logical state of the MCU
	bus. It does not show signal hold or setup times.
