2. The typical response time is the time required for 60% of devices to place a packet in the response memory
3. The maximum response time is the time required for 95% of devices to place a packet in the response memory
2. The reset command and the sleep command do not generate a response. The response times are the time

an error occurs, the response will be available in a shorter amount of time.

5 % of the devices may be slower than this number. The Host is expected to read the STATUS
register to determine when a response is available (see Appendix G).
