Port C and D reset output level options
Either of the following two options may be selected for the C and D I/O ports. Note that these options are specified in 4-
bit units.
Port output configuration option
All shared-function I/O ports have an open-drain output circuit in the LC65E1104.
Watchdog reset option
This option specifies the use of the PE1/WDR pin. This pin can be specified to function either as the normal port PE1 or
as the WDR watchdog reset pin.
Usage Notes
1. Option specification
The SU60K.EXE program is used for option specification. The option code for the option specification area
(addresses 1000 to 100A (hexadecimal)) is created by assembling the output of the SU60K.EXE program using the
Sanyo M60K.EXE macro assembler and then linking the macro assembler output with the Sanyo L60K.EXE linker.
It is also possible to load data directly into the option specification area. Specify options according to the option code
creation table on page 8.
2. PROM programming
LC65E1104 can be programmed with a general-purpose EPROM programmer using either the W65EP1104D or
W65EP1104M adapter.
Recommended EPROM programmers
The Intel 27512 (VPP: 12.5 V) high-speed programming method must be used to program this device. The address
range must be set to 0 to 100A (hexadecimal) and the DASEC jumper must be set to the off position.
3. Using the data security function
The data security function prevents data already written to the microcontroller's PROM from being overwritten.
LC651104 data security function procedure
Move the DASEC jumper on the EPROM programming pin adapter to the on position. This enables the data
security function.
Attempt to reprogram the EPROM.
Since the data security function is enabled, the EPROM programmer will display an error. Note that this error is not
due to an error in either the programmer or the LSI.
No. 5221-6/19
