Command set
All bus write operations to the device are interpreted by the Command Interface. The
Commands are input on I/O0-I/O7 and are latched on the rising edge of Write Enable when
the Command Latch Enable signal is high. Device operations are selected by writing
specific commands to the Command Register. The two-step command sequences for
program and erase operations are imposed to maximize data security.
The Commands are summarized in Table 9.

Bus Write operations(1)(2)
1.
The bus cycles are only shown for issuing the codes. The cycles required to input the addresses or
input/output data are not shown.
2.
Any undefined command sequence will be ignored by the device.
