General Asynchronous Link Error Codes
(STS, EXT STS)
Appendix C
CĆ3
You will have an EXT STS code if your STS code is F0 (hex). The EXT
STS has different definitions depending on the command code (type of
command). If the command code is:
00 to 08 (hex) then there is not an EXT STS byte
09 to 0D (hex) then these command codes are not defined so the EXT
STS code is not defined
0E or 0F (hex) then the codes are defined in the sections below
The following table contains EXT STS codes (in hex) that you may find if
the command code is 0E (hex).
