Mode
The Power Down is low power idle state controlled by CE2. CE2 Low drives the
device in power down mode and mains low power idle state as long as CE2 is kept
low. CE2 High resume the device from power down mode.
This device has three power down modes, Sleep, 16M Partial, and 32M Partial.
The selection of power down mode is set through CR Set sequence. Each mode
has following data retention features.
The default state is Sleep and it is the lowest power consumption but all data will
be lost once CE2 is brought to Low for Power Down. It is not required to perform
CR Set sequence to set to Sleep mode after power-up in case of asynchronous
operation.
