3.4 BUSY
DIO0 is used as Busy signalling: the BUSY pin is set high when the current command is being processed, and when the
device is not ready to accept a new command.
Therefore, the timing diagram of the BUSY signal is as follows:
Figure 3-3: BUSY Timing Diagram
The amount of time the BUSY line will stay high after the end of rising edge of NSS (T
SW
Mode) depends on the nature of the
command. The most common switching times T
SW
Mode are indicated in Section 2.6 "Modes Transitions & Timings" on page
