Description
0:3 ROOT_MUX RW R 0 Selects a clock path as the root of HFCLK<k> and for
SRSS DSI input <k>. Use CLK_PATH_SELECT[i] to
configure the desired path. Some paths may have FLL
or PLL available (product-specific), and the control and
bypass mux selections of these are in other registers.
Configure the FLL using CLK_FLL_CONFIG register.
Configure a PLL using the related
CLK_PLL_CONFIG[k] register. 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.
PATH0 0 Select PATH0 (can be configured for FLL)
PATH1 1 Select PATH1 (can be configured for PLL0, if available
in the product)
PATH2 2 Select PATH2 (can be configured for PLL1, if available
in the product)
PATH3 3 Select PATH3 (can be configured for PLL2, if available
in the product)
PATH4 4 Select PATH4 (can be configured for PLL3, if available
in the product)
PATH5 5 Select PATH5 (can be configured for PLL4, if available
in the product)
PATH6 6 Select PATH6 (can be configured for PLL5, if available
in the product)
PATH7 7 Select PATH7 (can be configured for PLL6, if available
in the product)
PATH8 8 Select PATH8 (can be configured for PLL7, if available
in the product)
PATH9 9 Select PATH9 (can be configured for PLL8, if available
in the product)
