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