Bus operations
There are six standard bus operations that control the memory. Each of these is described
in this section, see
Command input
Command input bus operations give commands to the memory. Commands are accepted
when Chip Enable is Low, Command Latch Enable is High, Address Latch Enable is Low,
and Read Enable is High. They are latched on the rising edge of the Write Enable signal.
Only I/O0 to I/O7 input commands.
See
program erase endurance cycles
Address input
Address input bus operations input the memory address. Three bus cycles are required to
input the addresses (refer to Tables
Address insertion, x16
The addresses are accepted when Chip Enable is Low, Address Latch Enable is High,
Command Latch Enable is Low, and Read Enable is High. They are latched on the rising
edge of the Write Enable signal. Only I/O0 to I/O7 input addresses.

Data input
Data input bus operations input the data to be programmed.
Data is accepted only when Chip Enable is Low, Address Latch Enable is Low, Command
Latch Enable is Low, and Read Enable is High. The data is latched on the rising edge of the
Write Enable signal and is input sequentially using the Write Enable signal.
