maining address bits that are don’t care. When all necessary bits are set as
required, the programming equipment may then read the corresponding identi-
fier code on DQ7–DQ0.
To access the autoselect codes in-system, the host system can issue the autose-
lect command via the command. This method does not require V

The device includes two control functions which must be satisfied in order to ob-
tain data at the outputs. CE# is the power control and should be used for device
selection. OE# is the output control and should be used to gate data to the output
pins if the device is selected. The device is power-up in an asynchronous read
mode. In the asynchronous mode the device includes two control functions which
must be satisfied in order to obtain data at the outputs. CE# is the power control
and should be used for device selection. OE# is the output control and should be
used to gate data to the output pins if the device is selected.
