be powered. Check for the appropriate voltage at the MCU’s V
The RKICS should leave the target MCU in reset with approximately
0 Vdc at the MCU’s RST pin. Verify this at the target MCU’s RST pin
and at J2 pin 4. If RST floats too high, the MCU may start and execute
code out of its FLASH memory. The RKICS should reset the MCU again
in step 8 when the software is started.
the Hardware while watching the MCU power LED.
If the MCU power LED does not light, there may be a problem with the
host PC communicating with the RKICS. Continue with step 9.
If the MCU power LED flickers a few times and then goes out, the host
PC is able to control the RKICS but communications may still not be
established with the MCU on the target system. As the flickering of the
MCU power LED indicates, the host PC is applying and removing power
to the RKICS board during this period. Use an oscilloscope to view the
voltages on TP1 and TP2 as the software tries to establish
communication with the MCU. Restart or retry the ICS08RKZ software
while looking at the signals. Using the side pin on P1 (DC INPUT jack)
as the ground reference, check for a signal that varies between 0 and
+7.5 Vdc at TP1 (V

If the MCU power LED comes on and stays on, communication probably
was established with the MCU. Check for the following voltages, using
the side pin on P1 (DC INPUT jack) as the ground reference:
If these voltages are present, the RKICS power is good. Continue with
step 9.
