NOTES:
1. The low-speed on-chip oscillator is used as the on-chip oscillator clock when the CM1 register CM14 bit=0 (low-
speed on-chip oscillator on) and HR0 register HR01 bit=0 (low-speed on-chip oscillator selected).
The high-speed on-chip oscillator is used as the on-chip oscillator clock when the HR0 register HR00 bit=1
(high-speed on-chip oscillator on) and HR01 bit=1 (high-speed on-chip oscillator selected).
