For the non-extended formats, the returned data for each fault consists of 21 words (42 bytes) for
00h and 01h and 23 words (46 bytes) for 41h. This request returns 16 Controller Fault Table entries
or 32 I/O Fault Table entries, or the actual number of faults, if fewer. If the fault table read is empty,
no data is returned.
The following tables show the return format of a Controller Fault Table entry and an I/O Fault Table
