External Commands

Parameter	Description
Release	Clears the previous external requests.
Forced Switch	The node switches to the selected clock source on an external request for forced switch. The node cannot be switched to other clock sources unless the external request is cleared. Forced switch has a higher priority over manual switch.
Manual Switch	The node explicitly force the SSM module to latch onto a higher quality/priority reference clock. This command cannot be issued if there is a lockout on the clock, or if the clock is in a signal fail state.
Lockout Source	This excludes the particular timing source from being considered for selection as a clock reference.
Clear Lockout	Clears the lock on the clock source so that the node can be synchronized to the clock source.
