4.2.2 Optimization of response speed during debugging

The communication speed of user system and MB2146-09 change by the operating
frequency of the target microcontroller. When the operating frequency is reduced,
especially in the sub clock mode, communication speed is also reduced. In this case,
optimize the communication speed. The function increasing the operating frequency
automatically is called clock-up mode. The default is ON at that time.
Also, this setting is performed at the setup wizard or [Setup] -> [Debug Environment]
-> [Debug Environment...] -> [Response speed] tab.
Note:
When the clock-up mode is used, the operating frequency is changed automatically
at breaking. If the failure is caused by changing the operating frequency, disable the
clock-up mode.
If a break occurs immediately after changing the system clock mode by the user
program, no clock up is performed during oscillations stabilization wait state. Clock
up will be performed when oscillations are stabilized.
