9.2.12 High-Speed On-Chip Oscillator Control Register 2 (HOCOCR2)
Note: Set the PRCR.PRC0 bit to 1 (write enabled) before rewriting this register.
High-speed on-chip control register 2 is used to set operation of the high-speed on-chip oscillator.
When the HOCOCR.HCSTP bit is 0 (HOCO is operating), do not write to the HOCOCR2 register.
