The rising edge of E starts a timer delaying the internal
programming cycle 100
μ
s. Therefore, each successive
write operation must begin within 100
μ
s of the last byte
written. The following waveforms illustrate the sequence
and timing requirements.
PAGE WRITE OPERATION
Regardless of the microcontroller employed, the X68257
supports page mode write operations. This allows the
microcontroller to write from 1 to 128 bytes of data to the
X68257. Each individual write within a page write opera-
tion must conform to the byte write timing requirements.
Page Write Timing Sequence for E Controlled Operation

must be the same.
