Figure 4. Program Operation
Unlock Bypass Entry Command
The Unlock Bypass command, once issued, is used to bypass the
unlock
sequence for program,
chip erase, and CFI commands. This feature permits slow PROM programmers to significantly im-
prove programming/erase throughput since the command sequence often requires microseconds
to execute a single write operation. Therefore, once the Unlock Bypass command is issued, only
the two-cycle program and erase bypass commands are required. The Unlock Bypass Command
is ignored if the Secured Silicon sector is enabled. To return back to normal operation, the Unlock
Bypass Reset Command must be issued.
The following four sections describe the commands that may be executed within the unlock by-
pass mode.
Unlock Bypass Program Command
The Unlock Bypass Program command is a two-cycle command that consists of the actual pro-
gram command (A0h) and the program address/data combination. This command does not
require the two-cycle
unlock
sequence since the Unlock Bypass command was previously issued.
As with the standard program command, multiple Unlock Bypass Program commands can be is-
sued once the Unlock Bypass command is issued.
To return back to standard read operations, the Unlock Bypass Reset command must be issued.
The Unlock Bypass Program Command is ignored if the Secured Silicon sector is enabled.
