Note on Operating Frequency:
• You can not use the M30830T-EPB with a main clock (XIN-XOUT) less than 1 MHz. Contact your
nearest distributor to use it under the condition.
IMPORTANT
Note on Downloading Programs:
•When specifying a DRAM refresh interval, take note that when setting downloading a program to
an internal ROM area and setting software breaks, the main clock operates in the divide-by-8 mode.
Notes on Address-Match Interrupt:
•Do not single-step an address where an address-match interrupt occurs.
• When using the address-match interrupt, do not check the box of "Use Address Interrupt Break"
in the MCU tab of the Init dialog box. When not using the address-match interrupt, check the box.
• When you use address-match interrupt breaks, if a low reset is input during a user program
execution, a debug monitor program (about 100 cycles) is executed after the reset is released. Take
note that it has effects on the user program execution time and the result of a trace.
Note on On-chip Oscillator:
• Take note that you can not debug a program using the oscillation stop detection function (on-chip
oscillator). If you use the function, be sure to evaluate a system with an actual MCU.
Notes on Service-Life of the MCU's Internal Flash ROM:
•With the M30830T-EPB, programs are downloaded to the MCU's flash ROM when debugging in
the single-chip mode and memory expansion mode. Because the number of write/erase cycles of
this ROM is limited, the ROM must be replaced when at the end of its service-life.
• If the following errors occur frequently during program download, replace the emulation probe.
Flash ROM erase error ERROR (16258)
Flash ROM verify error ERROR (16259)
To purchase the product for replacement, contact your nearest distributor.
Note on PLL Clock:
• The PLL clock can be used as a clock for peripheral functions only. You can not debug your
program using it as a CPU clock. To use the PLL clock as a CPU clock, be sure to evaluate your
system with an actual MCU.
Note on Support for M32C/81 and 82 Groups:
• The M30830T-EPB has the M30835FJGP of M32C/83 Group as an evaluation MCU. Because of
the differences of ROM and RAM sizes and peripheral functions, to develop a program for an
M32C/81 or 82 Group MCU, refer to the User's Manual of M32C/81, 82 Group MCUs.
