Unlock Bypass Command Sequence
The unlock bypass feature allows faster programming than the standard program
command sequence. The unlock bypass command sequence is initiated by first
writing two unlock cycles. This is followed by a third write cycle containing the
unlock bypass command, 20h. The device then enters the unlock bypass mode.
A two-cycle unlock bypass program command sequence is all that is required to
program in this mode. The first cycle in this sequence contains the unlock bypass
program command, A0h; the second cycle contains the program address and
data. Additional data is programmed in the same manner. This mode dispenses
with the initial two unlock cycles required in the standard program command se-
