Error Checkpoint
Communication error occurred.
Data was not sent to the target.
Check that all emulator debugger settings, interface cable settings
and switches on the rear of the PC7501 match.
See the user's manuals of the PC7501 and emulator debugger.
User system cannot be properly built. (1) Download the proper firmware.
See "4.2 Downloading Firmware" (page 48).
(2) Check that the connection between the PC7501 and this product.
See "3.4 Connecting the PC7501" (page 33).
M3T-PD30F version is not the same version
as the firmware in the target.
Download the proper firmware.
See "4.2 Downloading Firmware" (page 48).
Target MCU is in the reset state. (1) Check that the reset pin of the user system is pulled up.
(2) Check that the reset pin of the user system has changed from
Low to High level.
Target MCU cannot be reset. (1) Check that pin NMI* is held High.
(2) If in memory expansion mode or microprocessor mode, check
pins RDY* and HOLD* are held High.
(3) If the reset circuit of the user system has a watchdog timer,
disable the timer.
(4) Check that power is properly supplied to the user system and that
the user system is properly grounded.
Target is in "HOLD" state. (1) If in memory expansion mode or microprocessor mode, check
pins RDY* and HOLD* are held High.
(2) The MCU is either in stop mode or wait mode. Either reset the
MCU or cancel the mode with an interrupt.
See MCU specifications.
Target clock is stopped. Check that the oscillator circuit of the user system is oscillating
properly.
Target MCU is not receiving power. Check that power is properly supplied to the user system and that the
user system is properly grounded.
