The page write mode can be initiated during any write operation. Following the initial byte write cycle, the host can write an additional one t0 127 bytes in the same manner as the first byte was written. Each successive byte load cycle, started by the WE HIGH to LOW transition, must begin within 100~s of the falling edge of the preceding WE. If a subsequent WE HIGH to LOW transition is not detected within 100ccs. the internal
