Considerations for Efficient Programming
Chip Erase
To program and verify the Atmel
the following sequence is recommended (See instruction formats in
The following algorithm puts the device in High-voltage Serial Programming mode:
1. Apply 4.5 - 5.5V between V
2. Set RESET pin to “0” and toggle SCI at least six times.
3. Set the Prog_enable pins listed in
4. Apply V
5. Shortly after latching the Prog_enable signature, the device will activly output data on
6. Wait at least 50 µs before giving any serial instructions on SDI/SII.
Table 4-69.
The loaded command and address are retained in the device during programming. For effi-
cient programming, the following should be considered.
• The command needs only be loaded once when writing or reading multiple memory
• Skip writing the data value 0xFF that is the contents of the entire EEPROM (unless the
• Address High byte needs only be loaded before programming or reading a new 256 word
The Chip Erase will erase the Flash and EEPROM
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 EEPROM are
re-programmed.
Note:
