ERROR CODES
Error Buffer:
The error code buffer contains all detected errors since the last time the buffer war erased.  The buffer is written from left to right.  When an error occurs that is not yet in the error code buffer, it is written at the left side, and all other errors shift one position to the right.
Error Codes:
In the case of non-intermittent faults, clear the error buffer before begin the repair.  This will ensure that old error codes are no longer present.
If possible, check the entire content of the error buffer.  In some situations an error code is only the result of an other error code and not the actual cause. For example, a fault in the protection detection circuitry can also lead to a protection.
