The minimum period for the Serial Clock Input (SCI) during High-voltage Serial Programming is
220 ns.
Table 20-14. Pin Values Used to Enter Programming Mode
To program and verify the ATtiny25/45/85 in the High-voltage Serial Programming mode, the fol-
lowing sequence is recommended (See instruction formats in
