clock source priority

Function

The clock source priority command configures a priority for a BITS clock source.

The undo clock source priority command deletes a priority for a BITS clock source.

By default, the clock source has the priority 0. That is, this clock source does not participate in clock source selection.

Parameters

Parameter	Description	Value
bits0	Indicates that the external BITS clock source is a BITS0 interface.	-
priority priority-value	Priority of a clock source.	The value is an integer ranging from 1 to 255. A smaller value indicates a higher priority.

Parameter

Description

Usage Guidelines

Usage Scenario

To enable this clock source to participate in clock source selection, configure a priority for this clock source.

Precautions

If SSM levels are not configured to participate in clock source selection, the device selects a clock source based on the priorities of clock sources.

If SSM levels are configured to participate in clock source selection, the device preferentially selects a clock source based on the SSM levels. If multiple clock sources have the same highest SSM level, the device selects a clock source based on the priorities of these clock sources.

Example

# Set the priority of the BITS0 to 15.
