Resume from Deep Power-down
In order 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 com-
mand is the only command that the device will recognize 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.
