*1 : Both of these reset commands are equivalent.

*2 : This command is valid during Fast Mode.

*3 : This command is valid while RESET = VID (except during HiddenROM MODE) .

*4 : The data “00h” is also acceptable.

*5 : The fourth bus cycle is only for read.

Notes : • Address bits A18 to A11 = X = “H” or “L” for all address commands except or Program Address (PA) and

Sector Address (SA) .

• Bus operations are defined in “MBM29LV800TE/BE User Bus Operations (BYTE = VIH)” and

“MBM29LV800TE/BE User Bus Operations (BYTE = VIL)”.

• RA = Address of the memory location to be read.

IA = Autoselect read address that sets A6, A1, A0.

PA = Address of the memory location to be programmed. Addresses are latched on the falling edge of

the WE pulse.

SA = Address of the sector to be erased. The combination of A18, A17, A16, A15, A14, A13, and A12 will

uniquely select any sector.
