Considerations for Efficient Programming
Chip Erase
Table 4-77.
The following algorithm puts the device in parallel programming mode:
The loaded command and address are retained in the device during programming. For effi-
cient 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 EEPROM are
reprogrammed.
Note:
1. Apply 4.5 - 5.5V between Vcc and GND.
2. Set RESET to “0” and toggle XTAL1 at least six times.
3. Set the Prog_enable pins listed in
4. Apply 11.5 - 12.5V to RESET. Any activity on Prog_enable pins within 100ns after
5. Wait at least 50 µs before sending a new command.
• 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
