9.6.3 Configuration

You must specify a block of memory in SRAM for the Micro Trace Buffer (MTB.) The block must be minimum 128 bytes.

Using the Buffer combo box, you can either:

• choose a global variable from the drop-down menu (e.g., volatile int buff[128];)

  

• specify the start address and size in the format of address;size (e.g., 0x2000000;0x100)

  

If you do not configure the buffer correctly (e.g., if the specified memory block is outside of SRAM memory range or the size does not meet the minimum size requirement), a message dialog will pop up when you start MTB.

In the Mode combo box, you can select what to do when the MTB is full: Auto halt debugger, Auto stop trace, or Overwrite old data.
