Considerations for Efficient
Programming
Chip Erase
2466J–AVR–10/04
The following algorithm puts the device in Parallel Programming mode:
1. Apply 4.5 - 5.5V between V
2. Set RESET to “0” and toggle XTAL1 at least 6 times
3. Set the Prog_enable pins listed in Table 110 on page 263 to “0000” and wait at
4. Apply 11.5 - 12.5V to RESET. Any activity on Prog_enable pins within 100 ns
Note, if External Crystal or External RC configuration is selected, it may not be possible
to apply qualified XTAL1 pulses. In such cases, the following algorithm should be
followed:
1. Set Prog_enable pins listed in Table 110 on page 263 to “0000”.
2. Apply 4.5 - 5.5V between V
3. Wait 100 µs.
4. Re-program the fuses to ensure that External Clock is selected as clock source
5. Exit Programming mode by power the device down or by bringing RESET pin to
6. Entering Programming mode with the original algorithm, as described above.
The loaded command and address are retained in the device during programming. For
efficient programming, the following should be considered.

The Chip Erase will erase the Flash and EEPROM
bits are not reset until the program memory has been completely erased. The Fuse bits
are not changed. A Chip Erase must be performed before the Flash and/or the
EEPROM are reprogrammed.
Note:
Load Command “Chip Erase”
1. Set XA1, XA0 to “10”. This enables command loading.
2. Set BS1 to “0”.
3. Set DATA to “1000 0000”. This is the command for Chip Erase.
4. Give XTAL1 a positive pulse. This loads the command.
5. Give WR a negative pulse. This starts the Chip Erase. RDY/BSY goes low.
6. Wait until RDY/BSY goes high before loading a new command.

(CKSEL3:0 = 0b0000) If Lock bits are programmed, a Chip Erase command

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.
