Freescale Semiconductor, Inc. A Appendix A.1 MMDS Commands This section describes MMDS-specific commands. Use MMDS-specific commands as you would any other commands, typing them in the Command Line component, or inserting them into a command file. For further details about debugger commands, please see the debugger manual sections Appendix, Debugger Commands and Command Line Component. A.1.1 Baud Rate Command BAUD A.1.1.1 Short Description sets the communication baud rate. A.1.1.
Freescale Semiconductor, Inc. Ap p en d ix MMDS Commands Without a rate value, the command displays the Communications Baud Rate Specification dialog box for interactive rate selection. If the system does not support the requested rate, the red message, “Error: is not a supported baud rate.” appears in the Command Line window. Example: BAUD 57600 Changes the Baud Rate Command to 57600. A.1.2 Trigger Commands CT A.1.2.1 Short Description clear triggers. A.1.2.
Freescale Semiconductor, Inc. Ap p en d ix MMDS Commands CT * Clears all triggers. This command clears both triggers of a range definition, even though just one of the triggers is a parameter value. Example: If triggers C and D define a range, CT C clears both the triggers. ST A.1.2.4 Short Description set trigger. A.1.2.5 Syntax ST [id [[!] [(address | address range | ,) [(data | data range | ,) [(clips | ,) [LIR= (X | H | L)]]]] [;R | ;W| ;RW] [;D] ]] A.1.2.
Freescale Semiconductor, Inc. Ap p en d ix MMDS Commands address range: A range of addresses to trip the trigger. To specify a range, use starting and ending constants, or use a starting address and a length value: start-address[:mask][..end-address] or start-address[:mask][,length] If you include a mask value, the system comparison involves only the address bits that correspond to ones (1s) of the mask.
Freescale Semiconductor, Inc. Ap p en d ix MMDS Commands of Term A to H. Without a mask, the ST command uses the unmasked value 0x1F for the clips. Each trigger clip line has three options: H - High L - Low X - Don’t Care The bits of the clips and mask words are: Bit: 0 Signal: Group A- BRN 1 RED 2 ORG 3 YEL 4 GRN 6 LIR (active low) ;R: Trigger on a read bus cycle only. ;W: Trigger on a write bus cycle only. ;RW: Trigger on a read or write bus cycle.
Freescale Semiconductor, Inc. Ap p en d ix MMDS Commands A bit set in both the clips and masks sets the trigger to high (-H). A bit clear in clips, but set in masks, sets the trigger to low (-L). A bit clear in a mask means that the trigger does not depend on the state of the clip. Examples: STA 0x1000 Sets analyzer trigger A to match accesses at address $1000. STB , 4 Sets analyzer trigger B to match accesses with a value of 4, at any address. STC 8 20..
Freescale Semiconductor, Inc. Ap p en d ix MMDS Commands list: A list of trigger identifiers (A, B, C, or D), separated by comma or space characters. *: All triggers. A.1.2.9 Description The TD command disables specified triggers. Use the Set Trigger (ST) command to set triggers; use the Trigger Enable (TE) command to enable triggers. Use the Clear Triggers (CT) command to clear triggers. Example: TD A B Disables triggers A and B. Example: TD * Disables all triggers. TE A.1.2.
Freescale Semiconductor, Inc. Ap p en d ix MMDS Commands TE A B Enables triggers A and B. Example: TE * Enables all triggers. A.1.3 Bus Analyzer Commands ARM A.1.3.1 Short Description arm bus analyser. A.1.3.2 Syntax ARM A.1.3.3 Description The ARM command arms the bus analyzer. When armed, the analyzer records bus cycles while the emulator is executing user code. Arming the analyzer clears the current contents of the trace buffer. Use the disarm analyzer (DARM) command to disarm the analyzer.
Freescale Semiconductor, Inc. Ap p en d ix MMDS Commands A.1.3.5 Syntax DARM A.1.3.6 Description The DARM command disarms the bus analyzer. When disarmed, the analyzer does not record bus cycles. If the bus analyzer is disarmed already, this command does nothing. ARM arms the analyzer GE A.1.3.7 Short Description go to event. A.1.3.8 Syntax GE list | * [;B] ;B: Specifies a backward search; without this option, the command directs a forward search.
Freescale Semiconductor, Inc. Ap p en d ix MMDS Commands GF A.1.3.10 Short Description go to frame. A.1.3.11 Syntax GF frame frame: Frame number, in the range 1..8191. This number must be decimal number, regardless of the current default number base. A.1.3.12 Description The GF command moves the cursor to a specified trace buffer frame. If the command’s frame-number value is greater than the number of frames stored in the buffer, the command moves your display to the buffer’s last frame.
Freescale Semiconductor, Inc. Ap p en d ix MMDS Commands A.1.3.15 Description The GP command searches the analyzer trace buffer for a frame that matches the defined search pattern. (Use the SP command to define the pattern.) A forward search begins at the frame immediately following the current frame. A backward search begins at the frame immediately preceding the current frame. When the search finds a matching frame, the system positions the line cursor on the frame, in the center of the screen.
Freescale Semiconductor, Inc. Ap p en d ix MMDS Commands LF logfile Open the logging file. Example: LT Copy all the trace buffer to the logging file. Example: NOLF Close the logging file. SC A.1.3.19 Short Description set analyzer clock. A.1.3.
Freescale Semiconductor, Inc. Ap p en d ix MMDS Commands 500,000 Hz divided by an integer. Thus, 50000 is valid, but 49000 is not. (If you specify 49000, the system rounds the value up the the next higher valid frequency: 50000.) A.1.3.21 Description The SC command sets the source for the time tag clock, which increments the trace buffer time tag. If this command includes no parameter values, the command interpreter opens the Bus Analyzer Configuration dialog box.
Freescale Semiconductor, Inc. Ap p en d ix MMDS Commands !: The inversion operator, which applies to a single address or data value. Specifying !sets a pattern on addresses or data values other than the specified address or data value. address: Address part of the pattern, specified with an address constant: address [:mask] If you include a mask value, the system comparison involves only the address bits that correspond to ones (1s) of the mask.
