28.8.5

Programming the EEPROM

The EEPROM is organized in pages, see Table 29-8 on page 202. When programming the

EEPROM, the data is latched into a page buffer. This allows one page of data to be pro-

grammed simultaneously. The programming algorithm for the EEPROM Data memory is as

follows (refer to Table 28-15 on page 192):

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-

ming cycle to finish.

4. Repeat 2 through 3 until the entire EEPROM is programmed or until all data has been

programmed.

5. End Page Programming by Loading Command No Operation.

28.8.6

Reading the Flash

The algorithm for reading the Flash memory is as follows (refer to Table 28-15 on page 192):

1. Load Command "Read Flash".

2. Read Flash Low and High Bytes. The contents at the selected address are available at

serial output SDO.

28.8.7

Reading the EEPROM

The algorithm for reading the EEPROM memory is as follows (refer to Table 28-15 on page

192):

1. Load Command Read EEPROM.

2. Read EEPROM Byte. The contents at the selected address are available at serial output

SDO.

28.8.8

Programming and Reading the Fuse and Lock Bits

The algorithms for programming and reading the Fuse Low/High bits and Lock bits are shown in

Table 28-15 on page 192.

28.8.9

Reading the Signature Bytes and Calibration Byte

The algorithms for reading the Signature bytes and Calibration byte are shown in Table 28-15 on

page 192.

28.8.10 Power-off sequence

Set SCI to 0. Set RESET to 1. Turn V

power off.
