PROGRAM MEMORY READ PROCEDURE
The
PD75P116 can read the content of the program memory in the following procedure.
(1)
Pull down a pin which is not used to VSS via the resistor. A low-level signal is input to the X1 pin.
(2)
Supply +5 V to the VDD and VPP pins.
(3)
10
s wait.
(4)
The program memory address 0 clear mode.
(5)
Supply +6 V and +12.5 V respectively to VDD and VPP.
(6)
The program inhibit mode.
(7)
The verify mode. If clock pulses are input to the X1 pin, data is output sequentially 1 address at a time at
the period of inputting 4 pulses.
(8)
The program inhibit mode.
(9)
The program memory address 0 clear mode.
(10) Change the VDD and VPP pins voltage to +5 V.
(11) Power off.
The diagram below shows the procedure of the above (2) to (9).
