Cause 5:
Power might not be being supplied normally to the target device.
Action 5:
(1) Check the power supply setting.
(2) If the power is being supplied from the FP6, the power might not be sufficient. In such cases, supply
power from the target system. Confirm that the supply of power on the target system is possible.
Cause 6:
The security functions of the target device may restrict the connection to the PG-FP6.
Action 6:
None. Change the target device if this is required.
12.2.2 When an error produces the message ‘023 Inv. Sig. addr.’
Cause 1:
An attempt was made to connect a target device which differs from that when the settings file was created.
Action 1:
Create a new settings file or use the correct settings file with the target device.
Cause 2:
The memory structure might have been changed by the option settings of the target device.
Action 2:
When the MCU has a function that for changing the mapping of the flash memory, such as a dual-bank
structure, the FP6 recognizes the MCU as a different one before and after changes to the memory mapping.
Accordingly, after a change to the memory mapping in the MCU, the error “023 Inv. Sig. addr.” will occur. In
the FP6, create and change settings files for use before and after changes to the memory mapping.
12.2.3 When an error produces the message ‘Communication failure or timeout’
Cause 1:
The connection to the target system may be wrong.
Action 1:
Confirm that the connection to the target system is correct according to the recommended circuits shown in
chapter 11, Examples of Connections with Microcontrollers.
