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 copies)
or one floppy disk.
For the mask ROM confirmation and the mark specifications, refer
to the “Mitsubishi MCU Technical Information” Homepage
(http://www.infomicom.maec.co.jp/indexe.htm).
ROM PROGRAMMING METHOD
The built-in PROM of the blank One Time PROM version and built-in
EPROM version can be read or programmed with a general-purpose
PROM programmer using a special programming adapter
(PCA7447FP).
Fig. 45 Programming and testing of One Time PROM version
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 45 is recommended to verify programming.
