26.8.20 CLK_PATH_SELECT
Description:
Clock Path Select Register
Address:
0x40261200
Offset:
0x1200
Retention:
Retained
IsDeepSleep:
Yes
Comment:
Selects a source for clock path. The output of this mux can be used as the root of a clock tree.
If there is a PLL on the path, this mux output is the PLL reference clock. The related PLL
register contains a mux to select whether the clock path uses the PLL output or is bypassed to
the PLL reference clock.
Default:
0x0

Selects a source for clock PATH<i>. 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.
