How to write data in the user option specification area and the program area in the on-chip EPROM
(1) Writing option codes to the user option specification area
Use the cross assembler for the LC66516 mask programmed ROM-version microcontroller when you write option
codes in the user specification area. When your source application program is assembled, the option data will be
stored in the user option specification area (3FF8 through 3FFF). In addition to the above writing, you are allowed to
write option data directly into the user option specification area in the on-chip EPROM. In this case, making refer-
ences to the option code specification list on the next page will be a "must".
(2) Writing program into the on-chip EPROM program area
An EPROM writer available on your local market can be used to write program into the on-chip EPROM program
area. In this case, the EPROM writer (27128 EPROM writer) must be used together with the dedicated writer board
because the pin conversion (64 into 28) is required. The dedicated writer board is shown below.
Please note that the EPROM writer must be either an ADVANTEST product or the EVA800/850 accessory writer.
Such an EPROM writer enables you to write your application program into the EPROM in Intel high-speed writing
method.
This dedicated writer board is inserted into
the EPROM writer available on your local
market. (Select either an ADVANTEST
writer product or the EVA800/850 acces-
sory EPROM writer).

(3) How to erase the contents of the on-chip EPROM
To erase the contents of the on-chip EPROM, you can use an EPROM eraser available on your local market.
