NOTE. When the microcontroller is in Byte mode, the data on the lower half of the data bus, Port D, will be suppressed. If you want to acquire data on Port D (the lower 8-bits of the data port) while operating in the 8-bit bus mode, you will have to probe those pins separately by using some unused channels.

Operating Basics

Setting Up the Support

Information in this section is specific to the operations and functions of the TMS 241 68HC12 support on any Tektronix logic analyzer for which it can be purchased. Information on basic operations describes general tasks and functions.
Before you acquire and display disassembled data, you need to load the support and specify setups for clocking and triggering as described in the information on basic operations. The support provides default values for each of these setups, but you can change them as needed.

Channel Group Definitions

The software automatically defines channel groups for the support. If you want to know which signal is in which group, refer to the channel assignment tables beginning on page 1–2.
Show Cycles

Clocking

Custom Clocking
Clocking Options
Timing Considerations
A Show cycle is defined as any internal bus cycle made visible on the external bus. These types of cycles are acquired when you select Included.
A special clocking program is loaded to the module every time you load the 68HC12 support. This special clocking is called Custom.
With Custom clocking, the module logs in signals from multiple groups of channels at different times as they become valid on the 68HC12 bus. The module then sends all the logged-in signals to the trigger machine and to the memory of the module for storage.
The only clocking option available is 68HC12.
The data is clocked on both the rising and falling edge of the signal ECLK. The three stages for latching a complete data item follow:
1. The IPIPE Queue Movement information is clocked as the last stage of the
previous data item. Simultaneously as the first part of the cycle information was latched, the address is latched and held on the rising edge of the clock.
2. The data and the other control signals are clocked in on the falling edge of
the clock.
TMS 241 68HC12 Microcontroller Support Instruction Manual
2–1
Setting Up the Support
3. The last part of the cycle stores the IPIPE Execution information. The IPIPE
Execution information is stored on the rising edge of the previous data item (that was already latched).
The next data cycle starts by latching the address for the next data item.
For a given data item the address is latched first, then the data, control, and IPIPE Execution information, and finally the IPIPE Queue movement.
In analyzing the data, the IPIPE_X (IPIPE Execution) information is to be applied before the IPIPE_Q (IPIPE Queue) information.

Acquiring and Viewing Disassembled Data

Acquiring Data

Once you load the 68HC12 support and specify the trigger, you are ready to acquire and disassemble data.
If you have any problems acquiring data, refer to information on basic operations in your online help or Appendix A: Error Messages and Disassembly Pr oblems in the basic operations user manual.

Viewing Disassembled Data

You can view disassembled data in four display formats: Hardware, Software, Control Flow, and Subroutine. The information on basic operations describes how to select the disassembly display formats.
NOTE. Selections in the Disassembly property page (the Disassembly Format Definition overlay) must be set correctly for your acquired data to be disas­sembled correctly. Refer to Changing How Data is Displayed on page 2–8.
The default display format shows the Address, Data, and Control channel group values for each sample of acquired data.
If a channel group is not visible, you must use the Disassembly property page to make the group visible.
The disassembler displays special characters and strings in the instruction mnemonics to indicate significant events. Table 2–4 lists these special characters and strings, and gives a definition of what they represent.

Software Display Format
Control Flow Display
Format
The Software display format shows only the first fetch of executed instructions. Flushed cycles and extensions are not shown, even though they are part of the executed instruction. Read extensions will be used to disassemble the instruction, but will not be displayed as a separate cycle in the Software display format. Data reads and writes are not displayed.
In the Control Flow display format, only the first fetch of instructions that change the flow of control, or cause a branch in the addressing will be displayed.
If a conditional branch branches to an address that is reached sequentially, it might be impossible to determine if the branch was taken. If this happens the branch will not be displayed in the Control Flow display, and no flushing will be done by the software. Unconditional branches are always displayed whether or not the destination address is seen on the bus.
Instructions that unconditionally generate a change in the flow of control in the 68HC12 microcontroller are as follows:
BRA LBRA BSR CALL JMP JSR RTC RTS WAI RTI SWI TRAP
Instructions that conditionally generate a change in the flow of control in the 68HC12 microcontroller are as follows:
BCC BCS BEQ BGND BMI BNE BPL BVC BVS BHI BHS BLO BLS BGE BGT BLE BLT BRCLR BRSET LBCC LBCS LBEQ LBMI LBNE LBPL LBVC LBVS LBHI LBHS LBLO LBLS LBGE LBGT LBLE LBLT DBEQ DBNE IBEQ IBNE STOP TBEQ TBNE

Subroutine Display
Format
The Subroutine display format shows only the first fetch of subroutine call and return instructions. It will display conditional subroutine calls if they are considered to be taken.
Instructions that unconditionally generate a subroutine call or a return in the 68HC12 microcontroller are as follows:
BSR CALL JMP JSR RTC RTS WAI RTI SWI TRAP
Instructions that conditionally generate a subroutine call or a return in the 68HC12 microcontroller are as follows:
There are no conditional subroutine calls.

Changing How Data is Displayed

There are common fields and features that allow you to further modify displayed data to suit your needs. You can make common and optional display selections in the Disassembly property page (the Disassembly Format Definition overlay).
You can make selections unique to the 68HC12 support to do the following tasks.

Microprocessor Specific Disassembly Restrictions

The 68HC12 can function as a single chip microcomputer with all of the pins set up as I/O to control hardware. When the 68HC12 is operating in this mode the TMS 241 software cannot acquire program execution correctly. In order for the TMS 241 software to acquire useful disassembly, the 68HC12 must be config­ured so that the support can acquire bus activity.
2–10
TMS 241 68HC12 Microcontroller Support Instruction Manual
Acquiring and Viewing Disassembled Data
In order for the TMS 241 to successfully acquire data the 68HC12 must be configured so that the acquisition software has access to the following:
H ECLK (PE4) must be configured to stretch instead of free running in the
Mode Register.
H The 16-bits of the address: Port A and Port B H The data: either as an 8- or 16-bit data bus depending on the configuration;
Port C and Port D H The Pipe Status signals (PE[6-5]) The following signals are used, and have a small effect on the disassembler:
H The R/W signal (PE2) that distinguishes the read cycles from the write cycles H LSTRB (PE3) is used to distinguish the byte and word cycles; and which
byte is valid. H The mode register can be set to allow internal cycles from the internal
EEPROM and RAM to be visible on the external bus, which can also be
controlled by the mode select signals at reset time. H The reset line is monitored and used in the clocking algorithm of the support. The TMS 241 can provide support for: H Either an 8- or 16-bit bus. The system bus width can be selected in the
disassembly properties window, and defaults to a 16-bit bus.
H High address bits A16 through A21, Port G H Symbolic support for the chip select bits, Port F
Figure 2–3 shows a sample acquisition after power up reset. After power up reset, and until the ports are initialized, the Pipe Status signals are not set correctly and therefore disassembly is not reliable.
In Figure 2–3 the Data group is indicated to be in byte mode. The raw data group is not normally enabled, but it can be when you want to know what is on the entire bus when the control signals are correct.
You can use the Mark Opcode feature to force the disassembler to show mnemonics. In Figure 2–3 Sequence numbers 9 through 13 have been marked, and have the marking symbol >> preceding the mnemonic, and force the ( Byte Read ) to show the mnemonic.
