If DQ5 goes high during a program or erase operation, writing the reset com-
mand returns the device to the read mode (or erase-suspend-read mode if the
device was in Erase Suspend).
Note that if DQ1 goes high during a Write Buffer Programming operation, the
system must write the Write-to-Buffer-Abort Reset command sequence to reset
the device for the next operation.
Autoselect Command Sequence
The autoselect command sequence allows the host system to read several iden-
tifier codes at specific addresses:
Note: The device ID is read over three cycles. SA = Sector Address
The autoselect command sequence is initiated by first writing two unlock cycles.
This is followed by a third write cycle that contains the autoselect command. The
device then enters the autoselect mode. The system may read at any address
any number of times without initiating another autoselect command sequence:
The system must write the reset command to return to the read mode (or erase-
suspend-read mode if the device was previously in Erase Suspend).
Enter/Exit Secured Silicon Sector Command Sequence
The Secured Silicon Sector region provides a secured data area containing an
8-word/16-byte random Electronic Serial Number (ESN). The system can access
the Secured Silicon Sector region by issuing the three-cycle Enter Secured Sili-
con Sector command sequence. The device continues to access the Secured
Silicon Sector region until the system issues the four-cycle Exit Secured Silicon
Sector command sequence. The Exit Secured Silicon Sector command sequence
returns the device to normal operation. Table 30 on page 61 and Table 31 on
page 62 show the address and data requirements for both command sequences.
formation. Note that the ACC function and unlock bypass modes are not available
when the Secured Silicon Sector is enabled.
Word Program Command Sequence
Programming is a four-bus-cycle operation. The program command sequence is
initiated by writing two unlock write cycles, followed by the program set-up com-
mand. The program address and data are written next, which in turn initiate the
Embedded Program algorithm. The system is not required to provide further
controls or timings. The device automatically provides internally generated pro-
gram pulses and verifies the programmed cell margin. Table 30 on page 61 and
Table 31 on page 62 show the address and data requirements for the word pro-
gram command sequence, respectively.
