Note on Setting "1" to Protect Bit 2 (PRC2) with Sub Clock:
Note on Setting "1" to Protect Bit 2 (PRC2) in Division by 2 Mode:
Because this product emulates some I/O ports (P0 to P5, P10), you can not pullup ports P0 to P5 by the pullup
control registers, Install the included resistor arrays (51kΩ) as necessary.
The initial value of pullup control register 1 PUR1 of this product is different from that of an actual MCU.
When a VCC level is input to pin CNVss, the value of an actual MCU is “02h” (bit 1 PU11 is “1”), while that of
this product is “00h”.
When the CPU clock is set to the sub-clock (low-speed mode or low power dissipation mode), even if you
enable the PRC2 bit, writing to the register protected by the PRC2 bit (PD9, S3C and S4C) cannot be done
properly. When you enable the PRC2 bit and write to the register protected by the PRC2 (PD9, S3C and S4C),
do not set the CPU clock to the sub-clock.
With the M16C/60 Series MCUs, when a maskable interrupt is generated, the interrupt data (interrupt number
and interrupt request level) stored in addresses 00000h and 00001h are read out. Also, the interrupt request bit is
cleared when address 00000h or 00001h is read out. Consequently, when the address 00000h or 00001h readout
instruction is executed or when address 00000h or 00001h is read out in the cause of a program runaway, a
malfunction occurs in that the interrupt is not executed despite the interrupt request, because the request bit of
the highest priority interrupt factor enabled is cleared.
You can not use this product with a main clock (X
than 1MHz, contact your local distributor.
If you download, execute or single-step a program at a low operating frequency, a communication timeout error
may occur.
Once this command is executed, it remains effective the next time you start the emulator debugger. Therefore,
you do not need to execute this command again.
If the error still occurs in this setting, contact your local distributor.
Under the following conditions, even if you enable the PRC2 bit, writing to the register protected by the PRC2
bit (PD9, S3C and S4C) cannot be done properly.
Therefore, if the condition (1) or (2) applies, when you enable the PRC2 bit and write to the register protected
by the PRC2 (PD9, S3C and S4C), set the CPU clock neither to the main clock in division by 2 mode nor to the
on-chip oscillator clock in division by 2 mode.
Execute the command shown below in the Script Window after starting the emulator debugger.
(1) Between when stop mode is released and when a hardware reset is executed
(2) Between when low power dissipation mode is enabled and when a hardware reset is executed
