(Note 1) Always set "0" to the address bits [1:0] in the entire bus cycle. (Setting values to bits [7:2]
(Note 2) Bus cycles are "bus write cycles" except for the second bus cycle of the Read command,
(Note 3) In executing the bus write cycles, the interval between each bus write cycle shall be 15
(Note 4) The "Sync command" must be executed immediately after completing each bus write cycle.
(Note 5) Execute the "Sync command" immediately following the "LW command" after the fourth

Note) Select chip 0 or chip 1 with Addr[19].
Protection bit programming and protection bit erase are only available with chip 0.

the fourth bus cycle of the Read/reset command, and the fifth bus cycle of the ID-Read
command. Bus write cycles are executed by SW commands. Use "Data" in the table for the
store data of SW commands. The address [31:16] in each bus write cycle should be the
target flash memory address [31:16] of the command sequence. Use "Addr." in the table for
the address [15:0].
