Instr.4
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 - 7until 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 are
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 - 5 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.
Instr 5-7.
