Important information

• When debugging C8051F3xx/F4xx/F5xx/F7xx/F8xx/F9xx devices the Silabs 2-wire interface must be used. Enable this option on the Silabs Download page.

• The watchdog timer (WDT) is by default on, which could cause unexpected behavior, such as that the disassembly window displays data space instead of code space, due to the periodically triggered interrupt. If the WDT is not used we recommend you to disable it. This can be done in main, but in some cases this might be too late. So if needed, place the code for disabling the WDT in the low_level_init() function which is called from the cstartup code:

      __near_func __root char __low_level_init()
      {  
          /* code to disable WDT */
  
          return 1;  // non zero will initialize data segment
      }
              

• SFR paging (when supported by a specific device) is only applicable to the Register window and the Memory window in the debugger. Other C-Spy windows might display incorrect SFR values because they have no knowledge of the current SFR page. For example, in the Disassembly window, the incorrect SFR name might appear. The simulator driver does not support SFR paging at all.
