Driving Chip Select (S) High after the 8-bit instruction byte has been received by the device, but before

the whole of the 8-bit Electronic Signature has been transmitted for the first time (as shown in Figure 20),

still ensures that the device is put into Standby Power mode. If the device was not previously in the Deep

Power-down mode, the transition to the Standby Power mode is immediate. If the device was previously

in the Deep Power-down mode, though, the transition to the Standby Power mode is delayed by tRES1,

and Chip Select (S) must remain High for at least tRES1(max), as specified in Table 14. Once in the

Standby Power mode, the device waits to be selected, so that it can receive, decode and execute

instructions.
