8. Apply one clock pulse to X
9. Force the Port 2 pins with F0h .
10. Apply one clock pulse to X
11. Force the Port 2 pins with 0Fh .
12. Apply one clock pulse to X
13. Force the Port 2 pins with 00h .
14. Apply one clock pulse to X
15. Force the Port 2 pins with F1h .
16. Apply one clock pulse to X

18. Apply one clock pulse to X
19. The part is now in EPROM mode. The only way to exit EPROM mode is to
perform a POR.
All signals must be stable before the X
not change until X
for a minimum of 1µsec.
