The EEPROM is organized in pages, see Table 51 on page 107. 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 mem-
ory is as follows (refer to Table 55):
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
4. Repeat 2 through 3 until the entire EEPROM is programmed or until all data has
5. End Page Programming by Loading Command “No Operation”.
The algorithm for reading the Flash memory is as follows (refer to Table 55):
1. Load Command "Read Flash".
2. Read Flash Low and High Bytes. The contents at the selected address are avail-
The algorithm for reading the EEPROM memory is as follows (refer to Table 55):

The algorithms for programming and reading the Fuse Low/High bits and Lock bits are
shown in Table 55.
The algorithms for reading the Signature bytes and Calibration byte are shown in Table
