Table 139 Timeout Values
Command category is referred to “13 Command Protocol” on page 72.
The abbreviations “ns”, “us”, “ms” and “sec” mean nanoseconds, microseconds, milliseconds and seconds, respectively.
We recommend that the host system executes Soft reset and then retry to issue the command if the host system timeout would occur for the device.
