Latest Updated:08/01/2001

Question:

To operate this vector interrupt with the main clock, is it necessary to input an instruction that makes the CPU clock the main clock at the beginning of the vector interrupt?

No, this does not suffice.
It is necessary to start oscillation of the main clock after releasing the HALT mode, and after the oscillation stabilizes, switch to the main clock.
