Considerations for Efficient Programming
Chip Erase
Table 26-10. Command Byte Bit Coding
The following algorithm puts the device in Parallel Programming mode:
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:
The Chip Erase will erase the Flash and EEPROM

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
4. Apply 11.5 - 12.5V to RESET. Any activity on Prog_enable pins within 100 ns after
1. Set Prog_enable pins listed in
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 0b0.
6. Entering Programming mode with the original algorithm, as described above.
