•
Address bits A
19
to A
11
= X = “H” or “L” for all address commands except or Program Address (PA), Sector
Address (SA), and Bank Address (BA).
Bus operations are defined in “MBM29DL16XTE/BE User Bus Operations Tables (BYTE = V
IH
and
BYTE = V
IL
)”.
RA:
Address of the memory location to be read
IA :
Autoselect read address that sets both the bank address specified at (A
19
, A
18
, A
17
, A
16
, A
15
) and
all the other A
6
, A
1
, A
0
, (A
-1
).
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 erased. The combination of A
19
, A
18
, A
17
, A
16
, A
15
, A
14
, A
13
, and A
12
will
uniquely select any sector.
BA:
Bank Address (A
19
to A
15
)
RD:
Data read from location RA during read operation.
ID :
Device code/manufacture code for the address located by IA.
PD:
Data to be programmed at location PA. Data is latched on the rising edge of write pulse.
SPA: Sector group address to be protected. Set sector group address (SGA) and (A
6
, A
1
, A
0
) = (0, 1, 0).
SD:
Sector group protection verify data. Output 01h at protected sector group addresses and output
00h at unprotected sector group addresses.
HRA: Address of the HiddenROM area
29DL16XTE (Top Boot Type)
Word Mode: 0F8000h to 0FFFFFh
Byte Mode: 1F0000h to 1FFFFFh
29DL16XBE (Bottom Boot Type) Word Mode: 000000h to 007FFFh
Byte Mode: 000000h to 00FFFFh
HRBA: Bank Address of the HiddenROM area

The system should generate the following address patterns:
Word Mode: 555h or 2AAh to addresses A
10
to A
0
Byte Mode: AAAh or 555h to addresses A
10
to A
0
and A
–1
Both Read/Reset commands are functionally equivalent, resetting the device to the read mode.
Command combinations not described in Command Definitions table are illegal.

•
•
*1: Both of these reset commands are equivalent.
*2: This command is valid during Fast Mode.
*3: This command is valid while RESET = V
ID
(except during HiddenROM MODE).
*4: The valid addresses are A
6
to A
0
.
*5: This command is valid during HiddenROM mode.
*6: The data “00h” is also acceptable.
*7: The fourth bus cycle is only for read.
