5 CONNECTION TO TARGET SYSTEM
This section describes how to connect the S5U1C88816P to the target system.
Note: Turn the power of all equipment off before connecting or disconnecting cables.
(1) The I/O #1, I/O #2 and I/O #3 connectors are
used to connect the S5U1C88816P to the target
system.
Use the attached I/O connection cable (80-pin/
40-pin
×
2 flat type and 60-pin/30-pin
×
2 flat
type) for connection. Connect the 80-pin and
60-pin connectors to the S5U1C88816P side and
the 40-pin
×
2 and 30-pin
×
2 connectors to the
target system side.
Be careful as power (V
DD
) is supplied to I/O #1
and #2 connectors.
(2) If a clock of a frequency other than that gener-
ated
*
by the internal oscillation circuit is
necessary, an external clock can be used by
selecting the external clock option. Use the
function option generator (winfog) to select the
external clock input. When using the ICE, load
the function option HEX data (C8816XXX.FSA,
XXX is a customer code) to the ICE.
∗
The following shows the internal oscillation
clock frequencies:
OSC1 crystal oscillation: 32.768 kHz
OSC3 crystal oscillation: 4.9152 MHz
OSC3 ceramic oscillation: 8 MHz
When CR oscillation is selected for OSC1 or
OSC3, the oscillation frequency can be adjusted
using the variable resistor (VR2 for OSC1, VR3
for OSC3) on the S5U1C88816P. Since the CR
oscillation frequency monitor pins (OSC1CR for
OSC1 and OSC3CR for OSC3) are provided on
the board for connecting a frequency counter or
other equipment, use them when adjusting the
oscillation frequency. The initial CR oscillation
frequencies of OSC1 and OSC3 are undefined,
so they should be checked using the OSC1CR
and OSC3CR monitor pins.
