Communication Processor Module
16.11.7.5 USING THE TIME-SLOT ASSIGNER FOR SYNCHRONIZATION. The time-slot
assigner offers a method to internally synchronize a SMCx Transparent channel without
using the SMSYNx pin. This method is similar to that of the SMSYNx pin, except that the
synchronization event is not the falling edge of the SMSYNx signal, but the first time-slot for
this SMCx receiver/transmitter after the frame sync indication. Refer to Section 16.7 The
Serial Interface with Time-Slot Assigner for further information about configuring
time-slots for the SMCs and SCCs.
The time-slot assigner allows the SMCx receiver and transmitter to be enabled
simultaneously and synchronized, a capability that the SMSYNx pin does not provide. Refer
to Figure 16-119 for an example of synchronization using the time-slot assigner.
