time units before the data byte, DQ0-DQ7, is valid for reading.
Table 61. EEPROM WRITE Times (5V devices)
Note: 1. If the maximum time has elapsed between successive WRITE cycles to an EEPROM page, the transfer of this data to EEPROM
cells will begin. Also, bytes cannot be written (loaded) to a page any faster than the indicated minimum type.
2. These specifications are for writing a page to EEPROM cells.
