MFCLASS1-MFCODE2
The bytes MFCLASS1 and MFCLASS2 contain the error class, the bytes MFCODE1 and
MFCODE2 the error codes on a system error that has occurred in processing channel 1 or
2. MFCLASS and MFCODE together provide a 16-bit error code that describes the error
category and reason for the error, and the processing channel affected.
Error code:
XX - MFCLASS1 or MFCLASS2 (hex)
ZZ - MFCODE1 or MFCODE2 (hex)
