CHAPTER2 Dependence Functions
2.3.1.4 Operating Frequency
This section explains the setting of operating frequencies.
■ Operating frequencies
Set the operating frequencies of the MCU. The most suitable operating frequencies vary depending on the
type of DSU. DSU3 ranges from 1 to 200 MHz and DSU4 from 1 to 266 MHz. This setting provides the
optimum communication speed between the MCU and emulator.
This function can be controlled by the [Frequency] tab in debug environment setting dialog.
Notes:
• This setting is used to set maximum operating frequencies. Actual operating frequencies will not
be changed.
• Actual operating frequencies exceeding these settings will cause improper communication with
the emulator.
