High-voltage Serial Programming Algorithm
Enter High-voltage Serial Programming Mode
Considerations for Efficient Programming
To program and verify the ATmega8HVA/16HVA in the High-voltage Serial Programming mode,
the following sequence is recommended (See instruction formats in
The following algorithm puts the device in Serial (High-voltage) Programming mode:
1. Set Prog_enable pins listed in
2. Apply 3.0 - 3.5V between V
3. Wait 20 - 60 µs, and apply V
4. Keep the Prog_enable pins unchanged for at least t
5. Release Prog_enable[1] pin to avoid drive contention on the Prog_enable[1]/SDO pin.
6. Wait at least 300 µs before giving any serial instructions on SDI/SII.

Table 27-13. High-voltage Reset Characteristics
The loaded command and address are retained in the device during programming. For efficient
programming, the following should be considered.
• The command needs only be loaded once when writing or reading multiple memory locations.
• Skip writing the data value 0xFF that is the contents of the entire EEPROM (unless the
