Renesas RH850: Trace overflows

27-Nov-2023

Coding empty or very short program loops in embedded applications can cause CPU program trace overflows. Too many branches coming in succession are overwhelming the internal CPU trace logic that just can’t keep up with a torrent of branch messages. Possible solutions are:

  • Snooze
  • Halt instruction
  • Low power mode
  • Configuring trace trigger and qualifier
