7.2.5 Status and report
Title | Data | Data Name | No |
(1) Response format
- The response consists of a status and a report. Whether to return a CD report as a report depends on the command. The periodic response always returns a CD report.
The status and CD report are collectively called CD status information.
(2) Status
- When the status is FFH, it indicates REJECT (command invalid). The status code is always valid except during REJECT. Also, bit5 to bit7 are exclusive and cannot be 1 at the same time.
