Figure 21. Release from Deep Power-down (RES) Instruction Sequence

Driving Chip Select (S) High after the 8-bit instruc-

tion byte has been received by the device, but be-

fore the whole of the 8-bit Electronic Signature has

been transmitted for the first time (as shown in Fig-

ure 21.), still ensures that the device is put into

Standby Power mode. If the device was not previ-

ously in the Deep Power-down mode, the transi-

tion 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.
