2.3.1 Overview of main clock settings
The following types of main clock settings are available.
For details, see
2.3.2 Main clock settings
.
(1) Using a clock generated from a 6 MHz resonator mounted in the QB-V850ESFJ3 as an internal clock.
(2) Using a clock generated from a resonator other than the 6 MHz resonator mounted in the QB-V850ESFJ3
as an internal clock.
Oscillation with the resonator on the target system is not supported. Therefore, the in-circuit emulator cannot
emulate the oscillation operation of the clock on the target system.
