8.3 Program Memory Read Procedure
The µ PD75P3216 can read program memory contents using the following procedure.
(1) Pull down unused pins to V
(2) Supply 5 V to the V
(3) Wait 10 µ s.
(4) Select the zero-clear program memory address mode.
(5) Supply 6 V to the V
(6) Select the verify mode. Apply four pulses to the X1 pin. Every four clock pulses will output the data stored in one
(7) Select the zero-clear program memory address mode.
(8) Return the V
(9) Turn off the power.
The following figure shows steps (2) to (9).
