9-4-5 Response Codes
Response codes are 2-byte codes that indicate the results of command execu-
tion. The first byte of the response code indicates the general results of execu-
tion and is called the main response code, or MRES. The second byte provides
further details on the results of execution and is called the sub-response code, or
SRES.
The following tables shows the relationship between the MRES and the execu-
tion results. Refer to Appendix D: Response Codes from the C200HX/HG/HE
CPU for details on all response codes including the SRES and actions for each.
