Description
0:2 REF_MUX RW R 0 Selects a source for clock clk_ref_hf. Note that not all
products support all clock sources. Selecting a clock
source that is not supported will result in undefined
behavior. It takes four cycles of the originally selected
clock to switch away from it. Do not disable the original
clock during this time.
