Notes 1.
Selection items for standard settings (TYPE settings on Flashpro III) on the dedicated flash programmer
Flashpro IV.
2.
The possible setting range differs depending on the voltage. For details, refer to
CHAPTER 25
ELECTRICAL SPECIFICATIONS
.
3.
Because factors other than the baud rate error, such as the signal waveform slew, also affect UART
communication, thoroughly evaluate the slew as well as the baud rate error.
Remark
The items in parentheses in the Standard Setting column indicate the setting value or setting item of
Flashpro III when it differs from Flashpro IV.
