Instr.4
ATtiny24A/44A/84A
Operation Remarks
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.
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 - 6 for each new
address. Wait after Instr. 6 until
SDO goes high.
Instr. 5-6
Enter EEPROM Read mode.
Repeat Instr. 1, 3 - 4 for each
new address. Repeat Instr. 2 for
a new 256 byte page.
Wait after Instr. 4 until SDO
goes high. Write A - 3 = “0” to
program the Fuse bit.
Wait after Instr. 4 until SDO
goes high. Write F - B = “0” to
program the Fuse bit.
Wait after Instr. 4 until SDO
goes high. Write J = “0” to
program the Fuse bit.
