3.3 PROM READ PROCEDURE
The PROM contents can be read in the verify mode by using the following procedure: (see the following
figure)
(1) Pull unused pins to V
SS
through resistors. Set the X1 pin low.
(2) Supply 5 volts to the V
DD
and V
PP
pins.
(3) Wait for 10
μ
s.
(4) Select the clear program memory address mode.
(5) Supply 6 volts to the V
DD
and 12.5 volts to the V
PP
pins.
(6) Select the program inhibit mode.
(7) Select the verify mode. Apply four pulses to the X1 pin. Every four clock pulses will output the data stored
in one address.
(8) Select the program inhibit mode.
(9) Select the clear program memory address mode.
(10) Return the V
DD
and V
PP
pins back to + 5 volts.
(11) Turn off the power.
The following figure shows steps (2) to (9).
