= X = “H” or “L” for all address commands except for Program Address (PA),
Sector Address (SA) and Sector Group Address (SGA).
Bus operations are defined in “MBM29PL12LM User Bus Operations (Word Mode : BYTE = V
IH
)”
and “MBM29PL12LM User Bus Operations (Byte Mode : BYTE = V
IL
)”.
RA
= Address of the memory location to be read.
PA
= Address of the memory location to be programmed. Addresses are latched on the falling edge of
the write pulse.
SA
= Address of the sector to be programmed / erased. The combination of A

will uniquely select any sector. See “Sector Address Table (MBM29PL12LM)”.
SGA = Sector Group Address to be protected. See “Sector Group Address Table (MBM29PL12LM)”.
RD
= Data read from location RA during read operation.
PD
= Data to be programmed at location PA. Data is latched on the rising edge of write plus.
WBL = Write Buffer Location
HRA = Address of the HiddenROM area ;
Word Mode : 000000h to 000007h
Byte Mode : 000000h to 0000FFh
*1 : The command combinations not described in “MBM29PL12LM Standard Command Definitions” are
illegal.
*2 : Both of these reset commands are equivalent except for "Write to Buffer Abort Reset".
*3 : The Erase Suspend and Erase Resume command are valid only during a sector erase operation.
*4 : The Set to Fast Mode command is required prior to the Fast Program command.
*5 : The Reset from Fast Mode command is required to return to the read mode when the device is in fast mode.
*6 : Reset to the read mode. The Write to Buffer Abort Reset command is required after the Write to Buffer
operation was aborted.
*7 : This command is valid while RESET = V
ID
.
*8 : Sector Group Address (SGA) with A
6
= 0, A
3
= 0, A
2
= 0, A
1
= 1, and A
0
= 0
*9 : The valid address are A

to A
0
.
*10 : The HiddenROM Entry command is required prior to the HiddenROM programming.
*11 : This command is valid during HiddenROM mode.
*12 : The data “F0h” is also acceptable.
*13 : Indicates read cycle.
