Operation Remarks
Wait after Instr.3 until SDO goes
high for the Chip Erase cycle to
finish.
Enter Flash Programming code.
Repeat after Instr. 1 - 5 until the
entire page buffer is filled or until all
data within the page is filled. See
Note 1.
Wait after Instr 3 until SDO goes
high. Repeat Instr. 2 - 3 for each
loaded Flash Page until the entire
Flash or all data is programmed.
Repeat Instr. 1 for a new 256 byte
page. See Note 1.
Enter Flash Read mode.
Repeat Instr. 1, 3 - 6 for each new
address. Repeat Instr. 2 for a new
256 byte page.
Instr 5 - 6.
Enter EEPROM Programming
mode.
Repeat Instr. 1 - 4 until the entire
page buffer is filled or until all data
within the page is filled. See Note
2.
Wait after Instr. 2 until SDO goes
high. Repeat Instr. 1 - 2 for each
loaded EEPROM page until the
entire EEPROM or all data is
programmed.
Repeat Instr. 1 - 5 for each new
address. Wait after Instr. 5 until
SDO goes high. See Note 3.
