The following algorithm puts the device in Parallel (High-voltage) > Programming mode:

tive algorithm can be used.
The loaded command and address are retained in the device during programming. For effi-
cient programming, the following should be considered.
1. Set Prog_enable pins listed in Table 25-9. to “0000”, RESET pin to “0” and V
2. Apply 4.5 - 5.5V between VCC and GND. Ensure that V
3. Wait 20 - 60µs, and apply 11.5 - 12.5V to RESET.
4. Keep the Prog_enable pins unchanged for at least 10µs after the High-voltage has
5. Wait at least 300µs before giving any parallel programming commands.
6. Exit Programming mode by power the device down or by bringing RESET pin to 0V.
