APPENDIX A S5U1C88000P1&S5U1C88655P2 MANUAL (Peripheral Circuit Board for S1C8F626)
Use the I/O cables (80-pin/40-pin
× 2 flat type,
100-pin/50-pin
× 2 flat type, 40-pin/20-pin × 2 flat
type) to connect between the I/O #1 to I/O #4
connectors of the front panel and the target
system.
Connect the 80-pin, 100-pin and 40-pin cable
connectors to the I/O #1 to I/O #4 connectors, and
the 40-pin
× 2, 50-pin × 2 and 20-pin × 2 connectors
to the target system. Be careful as power (VDD) is
supplied to I/O #1, I/O #2 and I/O #3 connectors.

A.3 Connecting to the Target System
This section explains how to connect the S5U1C88000P1&S5U1C88655P2 to the target system.
Note: Turn the power of all equipment off before connecting or disconnecting cables.
The following shows the clock frequencies
generated from the on-board crystal oscillation
circuits:
OSC1 crystal oscillation circuit: 32.768 kHz
OSC3 crystal oscillation circuit: 4.9152 MHz
When CR oscillation is selected for OSC3, the
oscillation frequency can be adjusted using the
controls on the front panel (OSC3H and OSC3L).
Use a frequency counter or other equipment to be
connected to the OSC3 CR oscillation frequency
monitor pin (pin 19) on the monitor connector for
monitoring the frequency during adjustment. Be
sure of the frequency when using this monitor pin
because the CR oscillation frequency is initially
undefined.
