8.49 EXIT 4-BYTE ADDRESS MODE OPERATION (EX4B, 29h)

In order to be backward compatible, the Exit 4-byte Address Mode instruction allows 24bit address (A23-A0) to be

used to access the memory array up to 128Mb. The Bank Address Register must be used to access the memory

array beyond 128Mb. To execute EX4B operation, the host drives CE# low, sends the instruction code and then

drives CE# high.

A Write Enable (WREN, 06h) command is not required prior to EX4B (29h) command.

Notes:

The EX4B instruction will reset the Bit 7 (EXTADD) of the volatile Bank Address Register to “0” ”, but will not

change the non-volatile Bank Address Register.

Option-X for UNPWD = 29h & EX4B = E9h.
