(3) Power-supply connector: CN3
CN3 is connected to the power-supply cable that comes with this product or that comes with the
IE850A. When a base board is connected and emulation RAM (ERAM) or external tracing (Aurora
tracing) is used, be sure to connect the power-supply cable to CN3 and 5 V.
When disconnecting the power-supply cable from the emulation adapter, press the tabs on both sides
of the CN1 connector of the power-supply cable to unlock the connector.
CAUTION
Applied voltage:
Make sure that the voltage applied to CN3 is within the specified range (4.5 V to 5.5 V).
An applied voltage out of the range may cause the emulation adapter to emit smoke or
catch fire or otherwise be damaged.
CAUTION
Unlocking the connector:
Do not press the tabs for unlocking the connector too hard as this may lead to them
being stuck in this position. Take care on this point.
(4) Power-supply pin header: JP16
JP16 is a pin header which allows the monitoring of +5 V and GND that are supplied from CN2.
(5) Status LEDs
Name of LED
Specification
POWER
Illuminated: CN3 is supplying power.
Not illuminated: CN3 is not supplying power.
EMUVDD
Illuminated: VDD for debugging (EMUVDD) = ON
Not illuminated: VDD for debugging (EMUVDD) = OFF
This specification depends on the settings of JP1 or JP4.
EMUVCC
Illuminated: VCC for debugging (EMUVCC) = ON
Not illuminated: VCC for debugging (EMUVCC) = OFF
This specification depends on the settings of JP3.
(6) Jumper block: JP5 (VDD_SEL)
JP5 (VDD_SEL)
Specification
Open-circuit
Setting prohibited.
1-2 short-circuit
(default)
The VDD power generated from the emulation adapter is supplied to the VDD
power for the debug chip.
2-3 short-circuit
The VDD power on the target system is supplied to the VDD power for the debug
chip.
