Advance Information
Ta b l e 1 1 . Primary Vendor-Specific Extended Query
Command Definitions
Writing specific address and data commands or sequences into the command
register initiates device operations. Table 12 and Table 13 define the valid register
command sequences. Writing incorrect address and data values or writing them
in the improper sequence may place the device in an unknown state. A reset com-
mand is then required to return the device to reading array data.
All addresses are latched on the falling edge of WE# or CE#, whichever happens
later. All data is latched on the rising edge of WE# or CE#, whichever happens
first. Refer to the AC Characteristics section for timing diagrams.
