8. Apply one clock pulse to XIN.
9. Force the Port 2 pins with F0h.
10. Apply one clock pulse to XIN.
11. Force the Port 2 pins with 0Fh.
12. Apply one clock pulse to XIN.
13. Force the Port 2 pins with 00h.
14. Apply one clock pulse to XIN.
15. Force the Port 2 pins with F1h.
16. Apply one clock pulse to XIN.
17. Force the Port 2 pins with 00h.
18. Apply one clock pulse to XIN.
19. The part is now in EPROM mode. The only way to exit EPROM mode is to
perform a POR.
Note: All signals must be stable before the XIN (CE) pin is pulsed High and can-
not change until XIN (CE) pin is in a VIL state. The signal should be stable
for a minimum of 1µsec.
