5 OPERATION METHOD OF S5U1C6S3N2E2
5.1 Preparation
This section describes the common preparation work necessary when the S5U1C6S3N2E2 is used by itself
and when it is connected to the ICE.
Before doing the following, be sure to turn the POWER switch of the S5U1C6S3N2E2 off.
5.1.1 Creation of target system
Mount the LCD panel, keys, and switches on the board to build a target system. Use the I/O connector
and LCD connector supplied with the S5U1C6S3N2E2 to connect the S5U1C6S3N2E2 to the target system.
(For the pin layout of each connector, refer to Section 3.3, "S5U1C6S3N2E2 I/O and LCD Connectors".)
Note: There is some difference in specifications between the S5U1C6S3N2E2 and the actual CPU. Refer
to Section 6.2, "Differences from Actual IC" when building a target system.
5.1.2 Creation and installation of ROMs
Create the program ROMs, function option ROM and segment option ROM, and insert them into the
sockets of the S5U1C6S3N2E2.
• Program ROMs (two)
The program ROMs contain the application program machine code. Write the Intel-HEX format files
output by the HEX converter or the cross-assembler into EPROMs to create program ROMs. Since two
HEX files containing the high-order section (-H.HEX) and the low-order section (-L.HEX) of the
machine code are output, two EPROMs are created. Insert them into the socket H.HEX and L.HEX
under the top cover, respectively.
These ROMs are not effective when connecting the
S5U1C6S3N2E2 to the ICE. In addition, it is necessary to
write the object data into the EPROM attaching the offset
address as Table 5.1.2.1 according to the type of EPROM to
be used.
Table 5.1.2.1 Offset address
EPROM type Offset value
27C64 0000H (no offset)
27C128 0000H (no offset)
27C256 4000H
27C512 C000H
• Function option ROM (one)
The function option ROM is used to specify function options, such as I/O port specifications. Create
the function option ROM from the function option HEX file (-F.HEX) output by the function option
generator, and insert it into the F.HEX socket under the top cover.
This ROM is effective even when the ICE is connected, however, this ROM is disregarded due to the
loading of the data from the ICE.
• Segment option ROM (one)
The segment option ROM is used to specify segment options for LCD assignment and SEG terminal
output specifications. Create the segment option ROM from the segment option HEX file (-S.HEX)
output by the segment option generator, and insert it into the S.HEX socket in the top cover.
This ROM is effective even when the ICE is connected, however, this ROM is disregarded due to the
loading of the data from the ICE.
• EPROM specifications
Use EPROMs with the following specifications:
Program ROM: 27C64 to 27C512 (250 ns or less access time)
Function option ROM: 27C64 to 27C512 (250 ns or less access time)
Segment option ROM: 27C64 to 27C512 (250 ns or less access time)
