Description

Clock Root Select Register

Fields

ROOT_MUX

Selects a clock path as the root of HFCLK and for SRSS DSI input . Use CLK_SELECT_PATH[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.

0 (PATH0): Select PATH0 (can be configured for FLL)

1 (PATH1): Select PATH1 (can be configured for PLL0, if available in the product)

2 (PATH2): Select PATH2 (can be configured for PLL1, if available in the product)

3 (PATH3): Select PATH3 (can be configured for PLL2, if available in the product)

4 (PATH4): Select PATH4 (can be configured for PLL3, if available in the product)

5 (PATH5): Select PATH5 (can be configured for PLL4, if available in the product)

6 (PATH6): Select PATH6 (can be configured for PLL5, if available in the product)

7 (PATH7): Select PATH7 (can be configured for PLL6, if available in the product)

8 (PATH8): Select PATH8 (can be configured for PLL7, if available in the product)

9 (PATH9): Select PATH9 (can be configured for PLL8, if available in the product)

10 (PATH10): Select PATH10 (can be configured for PLL9, if available in the product)

11 (PATH11): Select PATH11 (can be configured for PLL10, if available in the product)

12 (PATH12): Select PATH12 (can be configured for PLL11, if available in the product)

13 (PATH13): Select PATH13 (can be configured for PLL12, if available in the product)

14 (PATH14): Select PATH14 (can be configured for PLL13, if available in the product)

15 (PATH15): Select PATH15 (can be configured for PLL14, if available in the product)
ROOT_DIV

Selects predivider value for this clock root and DSI input.

0 (NO_DIV): Transparent mode, feed through selected clock source w/o dividing.

1 (DIV_BY_2): Divide selected clock source by 2

2 (DIV_BY_4): Divide selected clock source by 4

3 (DIV_BY_8): Divide selected clock source by 8
ENABLE

Enable for this clock root. All clock roots default to disabled (ENABLE==0) except HFCLK0, which cannot be disabled.
