Read modes
Read operations can be performed in two different ways depending on the settings in the
Configuration Register. If the clock signal is ‘don’t care’ for the data output, the read
operation is Asynchronous; if the data output is synchronized with clock, the read operation
is Synchronous.
The Read mode and data output format are determined by the Configuration Register. (See
Configuration Register section for details). All banks supports both asynchronous and
synchronous read operations. The Multiple Bank architecture allows read operations in one
bank, while write operations are being executed in another (see Tables
Asynchronous Read mode
In Asynchronous Read operations the clock signal is ‘don’t care’. The device outputs the
data corresponding to the address latched, that is the memory array, Status Register,
Common Flash Interface or Electronic Signature depending on the command issued. CR15
in the Configuration Register must be set to ‘1’ for Asynchronous operations.
In Asynchronous Read mode, the WAIT signal is always deasserted.
The device features an Automatic Standby mode. During asynchronous read operations,
after a bus inactivity of 150 ns, the device automatically switches to the Automatic Standby
mode. In this condition the power consumption is reduced to the standby value I
outputs are still driven.
