) = (0, 0, 1, 0).
SD: Sector protection verify data. Output 01H at protected sector addresses and output 00H at unprotected
sector addresses.

*4: The data “00H” is also acceptable.
Read/Reset Command
The read or reset operation is initiated by writing the Read/Reset command sequence into the command register.
Microprocessor read cycles retrieve array data from the memory. The device remains enabled for reads until the
command register contents are altered.
The devices will automatically power-up in the read/reset state. In this case, a command sequence is not required
to read data. Standard microprocessor read cycles will retrieve array data. This default value ensures that no
spurious alteration of the memory content occurs during the power transition. Refer to the AC Read
Characteristics and Waveforms for the specific timing parameters.(See Figures 5.1 and 5.2.)
Autoselect Command
Flash memories are intended for use in applications where the local CPU alters memory contents. As such,
manufacture and device codes must be accessible while the device resides in the target system. PROM
programmers typically access the signature codes by raising A
9
to a high voltage. However, multiplexing high
voltage onto the address lines is not generally desired system design practice.
The device contains an Autoselect command operation to supplement traditional PROM programming
methodology. The operation is initiated by writing the Autoselect command sequence into the command register.
Following the command write, a read cycle from address XX00H retrieves the manufacture code of 04H. A read
cycle from address X001H returns the device code (MBM29LV017 = C8H). (See Tables 3.1 and 3.2.)
All manufacturer and device codes will exhibit odd parity with the MSB (DQ
7
) defined as the parity bit.
Sector state (protection or unprotection) will be informed address X0002H.
Scanning the sector addresses (A
20
, A
19
, A
18
, A
17
, A
16
) while (A
10
, A
6
, A
1
, A
0
) = (0, 0, 1, 0) will produce a logical
“1” at device output DQ
0
for a protected sector. The programming verification should be perform margin mode
on the protected sector. (See Table 2.)
To terminate the operation, it is necessary to write the Read/Reset command sequence into the register, and
also to write the Autoselect command during the operation, execute it after writing Read/Reset command
sequence.
