DATA REQUIRED FOR MASK ORDERS

The following are necessary when ordering a mask ROM produc-

tion:

(1) Mask ROM Order Confirmation Form

(2) Mark Specification Form

(3) Data to be written to ROM, in EPROM form (three identical cop-

ies)

ROM PROGRAMMING METHOD

The built-in PROM of the blank One Time PROM version and the

EPROM version can be read or programmed with a general purpose

PROM programmer using a special programming adapter. Set the

address of PROM programmer in the user ROM area.

The PROM of the blank One Time PROM version is not tested or

screened in the assembly process and following processes. To en-

sure proper operation after programming, the procedure shown in

Figure 72 is recommended to verify programming.
