SPA:Sector address to be protected. Set sector address (SA) and (A

) = (0, 0, 1, 0).
SD: Sector protection verify data. Output 01H at protected sector addresses and output 00H at unprotected
sector addresses.
Notes:
1. This command is valid while Fast Mode.
2. This command is valid while RESET= V
ID
.
3. The data "00H" is also acceptable.
Command Definitions
Device operations are selected by writing specific address and data sequences into the command register.
Writing incorrect address and data values or writing them in the improper sequence will reset the devices to the
read mode. Table 6 defines the valid register command sequences. Note that the Erase Suspend (B0H) and
Erase Resume (30H) commands are valid only while the Sector Erase operation is in progress. Moreover both
Read/Reset commands are functionally equivalent, resetting the device to the read mode.
Read/Reset Command
In order to return from Autoselect mode or Exceeded Timing Limits (DQ
5
= 1) to read/reset mode, the read/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 devices remain 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.
