Epson S1C62 Family ユーザーズマニュアル

This section describes the common preparation work necessary when the S5U1C62xxxE is used by itself
and when it is connected to the ICE. Connection method, refer to Chapter 5, "CABLE CONNECTION".
Check the S5U1C62xxxE operation by mounting the supplied diagnostic ROMs as instructed in the
"S5U1C62xxxE Manual". It is recommended that this test be performed periodically.
Before doing the following, be sure to turn the POWER switch of the S5U1C62xxxE off.

Mount the LCD panel, keys, and switches on the board to build a target system. Use the I/O connectors
and LCD connectors supplied with the S5U1C62xxxE to connect the S5U1C62xxxE to the target system.
(For the pin layout of each connector, see the "S5U1C62xxxE Manual".)

Note: There is some difference in specifications between the S5U1C62xxxE and the actual CPU. Refer to

Section 2.2 in the "S5U1C62xxxE Manual", "Differences from Actual IC" when building a target
system.

Program ROMs (two)

The program ROMs contain the application program machine code. Write the HEX files output by the
ASM62XX cross-assembler into EPROMs to create program ROMs. Since two HEX files containing the
high-order section (C2XXYYYH.HEX) and the low-order section (C2XXYYYL.HEX) of the machine code
are output, two ROMs are created. Insert H.HEX into socket H and L.HEX into socket L on the top
panel. These ROMs are not necessary when connecting the S5U1C62xxxE to the ICE.

  •

Function option ROM (one)

The function option ROM is used to specify function options, such as I/O ports. Create the option ROM
from the function option HEX file (C2XXYYYF.HEX) output by the function option generator, and
insert it into the ROM1 socket (F.HEX) in the top cover.

  •

Segment option ROMs (two)

...

Only for the models that have the segment option.

The segment option ROMs are used to specify segment output ports. Create two segment ROMs (with
the same contents) from the segment option HEX file (C2XXYYYS.HEX) output by the segment option
generator, and insert them into two S.HEX sockets in the bottom cover.

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

(170 ns or less access time)

Program ROMs (two)

Segment option ROMs
(two, behind the
bottom cover, S.HEX)

H

L

Function option ROM
(one, behined the top
cover, F.HEX)

Top of S5U1C62xxxE

Create the program ROMs, function option
ROM and segment option ROMs, and insert
them into the sockets of the S5U1C62xxxE.
When the S5U1C62xxxE is delivered, the
function option ROM and segment option
ROMs for a diagnostic program are already
installed. Replace them with the created
ROMs.
