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) or one floppy disk
For the mask ROM confirmation and the mark specifications, re-
fer to the “Mitsubishi MCU Technical Information” Homepage
(http://www.infomicom.maec.co.jp/).
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. Set the address of PROM programmer in the user ROM
area.
Table 14 Programming adapter
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 51 is recommended to verify programming.

Screening (Caution)
(150
°C for 40 hours)
Verification with
PROM programmer
Functional check in
target device
The screening temperature is far higher
than the storage temperature. Never
expose to 150
°C exceeding 100 hours.
