  1. These registers may be individually read and written at any time.
  2. These registers are for 8xxx family only.
  3. Registers 36/37 were previously defined as unsigned but a mains controller has always had the option to set negative power so these now reflect their true nature.

Page 142 – ECU Trouble Codes

 

  1. Reading register 0 effectively latches a copy of the trouble code list at that time and so allows the list to be read without risk of the contents changing until register 0 is re-read. This also applies to reading the short descriptive strings for the trouble codes (see following pages), so that the list of trouble codes can be read in one or more sections and then the associated strings read as needed. To see any updates to the list, the PC needs to re-read register 0 and so latch the list once more.
