To program and verify the ATtiny15L in the High-voltage Serial Programming mode, the
following sequence is recommended (See instruction formats in Table 25):
1. Power-up sequence:
2. The Flash array is programmed one byte at a time by supplying first the address,
3. The EEPROM array is programmed one byte at a time by supplying first the
4. Any memory location can be verified by using the Read instruction, which
5. Power-off sequence:
When writing or reading serial data to the ATtiny15L, data is clocked on the eigth rising
edge of the 16 external clock pulses needed to generate the internal clock. See Figure
31, Figure 32, and Table 26 for an explanation.
