Timings
The timing of BSY and DRQ in Status Register are shown in the table below.
Command category is referred to in section 11.0, "Command protocol" on page 71.
The abbreviations "ns", "
ยต
s
", "ms," and "sec" mean nanoseconds, microseconds, milliseconds, and sec-
onds, 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.
