The Resume instruction cannot be accepted if the previous Erase/Program Suspend operation was interrupted by

unexpected power-off. It is also required that a subsequent Erase/Program Suspend instruction not to be issued within a

minimum of time of t

SUS following a previous Resume instruction. (Please refer to Figure 7-34 and Figure 7-35).

Deep Power Down (B9h)

Executing the Deep Power Down instruction is the best way to put the device in the lowest power consumption. The

Deep Power Down instruction reduces the standby current (from I

CC1 to ICC2 as specified in AC characteristics). The

instruction is entered by driving the CS pin low following execution of the B9h instruction. (Please refer to Figure 7-36

and Figure 7-37).

The CS pin must go high exactly at the byte boundary (the latest eighth bit of instruction code been latched-in);

otherwise, the Deep Power Down instruction is not executed. After CS goes high, it requires a delay of tDP and the Deep

Power Down mode is entered. While in the Deep Power Down mode, the Release Deep Power Down / Device ID

instruction is used to restore the device to normal operation. All other instructions are ignored, including the Read Status
