The Deep Power-Down command will be ignored if an internally self-timed operation such as a program or erase cycle is

in progress. The Deep Power-Down command must be reissued after the internally self-timed operation has been

completed in order for the device to enter the Deep Power-Down mode.

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 tRDPD and return to 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.
