IMPORTANT
Notes on Setting "1" to Protect Bit 2 (PRC2) in Division by 2 Mode:
z Under the following conditions, even if you enable the PRC2 bit, writing to the register protected by the
PRC2 bit (PD9, S3C, and S4C registers) cannot be done properly.
(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
z Therefore, if the condition (1) or (2) applies, when you enable the PRC2 bit and write to the register protected
by the PRC2, do not set the CPU clock to the main clock in division by 2 mode.
Note on the Input Thresholds for the Pins P1_5/INT3, P1_6/INT4 and P1_7/INT5:
z With this product, regarding pins P1_5/INT3, P1_6/INT4 and P1_7/INT5, a device which port or data bus
inputs to and a device which INT interrupt inputs to are different as follows:
Device which port or data bus inputs to: Port emulation FPGA (input level: TTL)
Device which INT interrupt inputs to: Evaluation MCU for emulating peripheral functions (input level:
CMOS Schmidt)
Therefore, the port input level can be read as “H” immediately after an INT interrupt (falling), and the port
input level can be read as “H” immediately before an INT interrupt (rising).
Note on Input Level for KI0# to KI3#:
z With this product, the KI0# to KI3# are TTL input level using the port emulation FPGA although these are
the CMOS Schmidt input level with the actual MCU. Therefore, the wrong interrupt may occur near the
threshold of the TTL level (2.0V to 0.8V) when the input signal is slow changing.
Note on Shifting from On-chip Oscillator Mode to Stop Mode:
z Do not shift from on-chip oscillator mode or on-chip oscillator low power dissipation mode to stop mode.
Otherwise, this product cannot return by an interrupt.
Note on Debugging M16C/30P Group MCUs:
z The M16C/62P Groups MCUs are used as an evaluation MCU for this product. An initial value of the internal
reserved area expansion bit (PM13) for the M16C/62P Group is different from that of for the M16C/30P
Group.
(1) An initial value of the internal reserved area expansion bit (PM13) for the M16C/62P Group: 1
(2) An initial value of the internal reserved area expansion bit (PM13) for the M16C/30P Group: 0
When developing the program for the M16C/30P Group, be sure to set the initial value of the internal
reserved area expansion bit (PM13) to “0” in the program.
Note on Final Evaluation:
z Be sure to evaluate your system with an evaluation MCU. Before starting mask production, evaluate your
system and make final confirmation with a CS (Commercial Sample) version MCU.
