Note on Memory Access:
When you download a program to an internal ROM area and set software breaks, the main clock operates in
divide-by-8 mode. Keep it in mind when you specify a watchdog timer refresh interval.
With the M30850T3-CPE, programs are downloaded to the MCU’s flash ROM when debugging in single-chip
mode or memory expansion mode. Because the number of write/erase cycles of this ROM is limited, the ROM
must be replace when at the end of its service-life.
If the following errors occur frequently during program download, replace the MCU board.
With the M30850T3-CPE, as the power voltage cannot be change after powering on the user system, the
voltage detection circuit (brown-out detection reset (hardware reset 2)) cannot be used with this product.
The protect is not canceled when bit 2 of protect register PRCR (PRC2), which enables writing into the port P9
direction register and the function select register A3, is changed with the below procedure.
When setting memory expansion mode as a processor mode, it may be changed to memory expansion mode
temporarily before the user program itself changes from single-chip mode to memory expansion mode.
Take due consideration on this phenomenon in the following cases:
(1) Step execution of an instruction setting PRC2 to ("1")
(2) Setting a break point from an instruction setting PRC2 to ("1") to where the port P9 direction register or the
(3) Setting (“1”) PRC2 from the dump window or script window during user’s program execution
To purchase the product for replacement or request for repair, contact your local distributor.
(1) Immediately before executing the program after setting a software break
(2) Immediately after stopping the program when a software break is set
function select register A3 is set
Flash ROM erase error occurred ERROR (16258)
Flash ROM verify error occurred ERROR (16259)
