4.3.2.9 ClockSetClkMux
With this command the clock MUX 0 and MUX 1 can be configured to select the sources for AMC clocks (MUX
domain 0) and the sources for the backplane clocks (MUX domain 1). This configurations will be stored in NV
memory of the IPMC and will be restored after powerup.
For clock e-keying purposes the indirect clock descriptors of the carrier has to be set in case of direct back-
plane connection, e.g. when sourcing backplane clock 3A from AMC B4 TCLKD the corresponding descriptor
has to be provisioned (local clock resource 5, clock ID 8). So the IPMC can do clock match finding and send a
PICMG SetClockState command to the AMC in B4 with enable state in case of a match.
For additional information about clocking configuration, see chapter 4.5 Carrier Clocking.
