(3) Errors Occur When the Emulator Debugger Starts Up
(When the target system is not connected)
Table 6.3 Checkpoints of errors when starting up the emulator debugger (target is not connected)
6.3 Operation Differs from That of PROM Version MCUs
(1) Does Not Operate with Operating Frequencies (3.6 V to 5.5 V) Properly
With this product, you need to change the switch setting according to the operation voltage. Change
the setting as described below. For details, see "3.2 Setting Switches and Pullup Resistor" (page 25).
Error Checkpoint
Check all emulator debugger settings, interface cable
connection and switches on the rear of the PC4701 match.
See the instruction manuals of the PC4701 and the
emulator debugger.
(1) Download the proper firmware.
See "4.2 Downloading Firmware" (page 40).
(2) Recheck the connection between the PC4701 and
this product.
See "3.4 Connecting the PC4701 and Emulation Pod"
(page 33).
Download the proper firmware.
See "4.2 Downloading Firmware" (page 40).
The program may be uncontrollable in areas where
memory not allocated. Recheck the map setting.
(1) The MCU is either in the stop mode or wait mode.
Either reset the MCU or cancel the mode with an
interrupt.
See the MCU specifications.
(2) The program may be uncontrollable in areas where
memory not allocated. Recheck the map setting.
Check the switches in the emulation pod are correctly set.
See "3.2 Setting Switches and Pullup Resistor" (page 25).
