ATtiny26(L)
The following algorithm puts the device in parallel programming mode:
Step 2-7 must be completed within 64ms.
1. Set Prog_enable pins listed in Table 55 on page 110, RESET and Vcc to 0V.
2. Apply 4.5 - 5.5V between Vcc/AVcc and GND.
3. Wait at least 60us.
4. Apply between 4.5V - 5.5V (Same as on Vcc/AVcc) to RESET pin.
5. Wait at least 20us.
6. Apply between 11.5V - 12.5V to RESET pin.
7. Wait at least 10us.
8. Program fuses to internal clock mode, 8 MHz, with 64ms delay. (CKSEL[3..0] = 0100,
9. Exit Programming mode by power the device down or by bringing RESET pin to 0V.
10. Repeat step 1 to 7 too re-enter programming mode.
The loaded command and address are retained in the device during programming. For efficient
programming, the following should be considered.

SUT[1..0] = 10). If Lock bits are programmed, a Chip Erase command must be executed
before changing the fuses.
The command needs only be loaded once when writing or reading multiple memory
locations.
Skip writing the data value $FF, that is the contents of the entire EEPROM (unless the
EESAVE Fuse is programmed) and Flash after a Chip Erase.
Address high byte needs only be loaded before programming or reading a new 256-word
window in Flash or 256-byte EEPROM. This consideration also applies to Signature bytes
reading.
