12.4 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 then the opcode 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.
