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
Section 8: Configuration register 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 14 and 15).
9.1
Asynchronous read mode
In asynchronous read operations the clock signal is ‘don’t care’. The device outputs the data
corresponding to the address latched, such as 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 IDD4 and the
outputs are still driven.
