INPUT
When the device is first powered on, it will be reset to the read or standby mode, depending
upon the state of the control line inputs. In order to perform other device functions, a series of
command sequences are entered into the device. The command sequences are shown in the
“Command Definition Table” on page 12
codes). The command sequences are written by applying a low pulse on the WE or CE input
with CE or WE low (respectively) and OE high. The address is latched on the falling edge of
CE or WE, whichever occurs last. The data is latched by the first rising edge of CE or WE.
Standard microprocessor write timings are used. The address locations used in the command
sequences are not affected by entering the command sequences.
