Operation Remarks
Wait after Instr.3 until PB2
goes high for the Chip Erase
cycle to finish.
Repeat Instr.2 for a new 256
byte page. Repeat Instr.3 for
each new address.
Wait after Instr.3 until PB2
goes high. Repeat Instr.1,
Instr. 2 and Instr.3 for each
new address.
Wait after Instr.3 until PB2
goes high. Repeat Instr.1,
Instr. 2 and Instr.3 for each
new address.
Repeat Instr.2 and Instr.3 for
each new address.
Repeat Instr.1 and Instr.2 for
each new address.
Repeat Instr.1 and Instr.2 for
each new address.
Repeat Instr.2 for each new
address.
Wait after Instr.3 until PB2
goes high
Repeat Instr.2 for each new
address.
Repeat Instr.2 for each new
address
Wait after Instr.4 until PB2
goes high. Write 8 - 3 = “0” to
program the Fuse bit.
Wait after Instr.4 until PB2
goes high. Write 2, 1 = “0” to
program the Lock bit.
Reading 8 - 3 = “0” means the
Fuse bit is programmed.
