11.4. 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

pin must first be as serted 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

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

pin is deasserted, or if the

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.
