Step 1: Direct access to data EEPROM.
Step 2: Set the data EEPROM Address Pointer.
Step 3: Load the data to be written.
Step 4: Enable memory writes.
Step 5: Initiate write.
Step 6: Poll WR bit, repeat until the bit is clear.
Step 7: Hold PGC low for time P10.
Step 8: Disable writes.
Repeat steps 2 through 8 to write more data.
Note 1: See Figure 4-4 for details on shift out data timing.
