5.6.10 Peripheral hardware and source clocks
The following lists peripheral hardware and source clocks incorporated in the 78K0/Kx2-A microcontrollers.
Remark
The peripheral hardware depends on the product. See

Notes 1.
The 78K0/KB2-A is not provided with a subsystem clock.
2.
Do not start the peripheral hardware operation with the external clock from peripheral hardware pins
when the internal high-speed oscillation clock and high-speed system clock are stopped while the CPU
operates with the subsystem clock, or when in the STOP mode.
