13 / 27 page ![]() Continued from preceding page. Usage Notes 1. Option specification When using a Sanyo cross assembler with the LC66E5316, use the version called “LC66S.EXE” and specify the actual microcontroller to be evaluated with the CPU pseudo instruction in the source file. The port options must be specified in the source file. The cross assembler will create an option code list in the option specification area (locations 3FF0H to 3FFFH). It is also possible to directly set up data in the option specification area. If this is done, the options must be specified according to the option code creation table shown on the following page. 2. Writing the EPROM Use a special-purpose writing conversion board (the W66EP5316D for the DIP package, and the W66EP5316Q for the QFP package) to allow the EPROM programmers listed below to be used when writing the data created by the cross assembler to the LC66E5316. • The EPROM programmers listed below can be used. • The “27512 (VPP 12.5 V) Intel high-speed write” technique must be used to write the EPROM. Set the address range to location 0 to 3FFFH. The DASEC jumper must be off. 3. Using the data security function The data security function sets up the microcontroller in advance so that data that was written to the microcontroller EPROM cannot be read out. Use the following procedure to enable the LC66E5316 data security function. • Set the write conversion board DASEC jumper to the on position. • Write the data to the EPROM once again. At this time, since this function will operate, the EPROM programmer will issue an error. However, this error does not indicate that there was a problem in either the programmer or the LSI. Notes: 1. If the data at all addresses was “FF” at step 2, the data security function will not be activated. Notes: 2. The data security function will not be activated at step 2 if the “blank → program → verify” operation sequence is used. Notes: 3. Always return the jumper to the off position after the data security function has been activated. No. 5488-13/27 LC66E5316 ROM area Bit Option specified Option/data relationship 7 6 5 3FFEH 4 Reserved. Must be set to predefined data values. This data is generated by the assembler. 3 If the assembler is not used, set this data to ‘00’. 2 1 0 7 6 5 3FFFH 4 Reserved. Must be set to predefined data values. This data is generated by the assembler. 3 If the assembler is not used, set this data to ‘00’. 2 1 0 Manufacturer Models that can be used Advantest R4945, R4944A, R4943, or equivalent products Ando AF9704 AVAL — Minato Electronics MODEL1890A |
