Note On Dma Transfer; Note On Protect Register; Note On Operating Frequency; Notes On Internal Flash Rom Of The Mcu - Renesas M30290T-EPB User Manual

Note on DMA Transfer:

With this product, the program is stopped with a loop program to a specific address. Therefore, if a
DMA request is generated while the program is stopped, DMA transfer is executed. However, make
note that DMA transfer while the program is stopped may not be performed correctly. Also note that the
below registers have been changed to generate DMA transfer as explained here even when the program
is stopped.
(1) DMA0 transfer counter: TCR0
(2) DMA1 transfer counter: TCR1

Note on Protect Register:

The protect is not canceled when bit 2 of protect register PRCR (PRC2), which enables writing into the
port P9 direction register and the SI/Oi control register, is changed with the below procedure.
(1) Step execution of an instruction setting PRC2 to "1"
(2) Setting a break point between an instruction setting PRC2 to "1" and a point where the port P9
direction register or the SI/Oi control register is set
(3) Setting PRC2 to "1" by the memory window or script window

Note on Operating Frequency:

You can not use this product with a main clock (X
less than 1 MHz, contact your local distributor.

Notes on Internal Flash ROM of the MCU:

This product downloads a user program to the flash ROM in an MCU. By checking "Disable the Internal
Flash ROM" in the MCU tab of the MCU setting dialog box of the emulator debugger, you can disable
the operation of the internal flash ROM of the MCU to use the emulation memory. However, the
maximum operating frequency is 10 MHz.
Because the number of write/erase cycles of the internal flash ROM of the MCU is limited, it must be
replaced at the end of its service-life. If the following errors occur frequently when downloading a
program, replace the MCU board.
(1) Flash ROM erase error occurred ERROR (16258)
(2) Flash ROM verify error occurred ERROR (16259)
To purchase products for replacement, contact your local distributor.
