The EEPROM is organized in pages, see
When programming the EEPROM, the data is latched into a page buffer. This allows one page
of data to be programmed simultaneously. The programming algorithm for the EEPROM Data
memory is as follows (refer to
1. Load Command “Write EEPROM”.
2. Load EEPROM Page Buffer.
3. Program EEPROM Page. Wait after Instr. 2 until SDO goes high for the “Page Program-
