Figure 183. Time-out values
Command category is referred to in Section 10.0  , “Command Protocol” on page 95.
The abbreviations "ns", "us", "ms," and "sec" mean nanoseconds, microseconds, milliseconds, and
seconds, respectively.
If the host detects a time-out while waiting for a response from the device, we recommend that the host
system execute a Soft reset and then retry the command.
