Figure 12-3. Deep Power-Down
Resume from Deep Power-Down
In order to exit the Deep Power-Down mode and resume normal device operation, the Resume from Deep Power-
Down command must be issued. The Resume from Deep Power-Down command is the only command that the
device will recognized while in the Deep Power-Down mode.
To resume from the Deep Power-Down mode, the CS pin must first be asserted and opcode of ABh must be
clocked into the device. Any additional data clocked into the device after the opcode will be ignored. When the CS
pin is deasserted, the device will exit the Deep Power-Down mode within the maximum time of t
the standby mode. After the device has returned to the standby mode, normal command operations such as Read
Array can be resumed.
If the complete opcode is not clocked in before the CS pin is deasserted, or if the CS pin is not deasserted on an
even byte boundary (multiples of eight bits), then the device will abort the operation and return to the Deep Power-
Down mode.
