Example
In CFI-mode 0 all four CFI-ports shall be initialized as IOM-2 ports with a 4-bit C/I-field
and D-channel handling by the SACCO-A.
CFI time slots 0, 1, 4, 5, 8, 9
initialized.
CFI time slots 2, 3, 6, 7, 10, 11,
need to be initialized:
CFI-port 0, time slot 2 (even), downstream
CFI-port 0, time slot 3 (odd), downstream
CFI-port 0, time slot 2 (even), upstream
CFI-port 0, time slot 3 (odd), upstream
Repeat the above programming steps for the remaining CFI-ports and time slots.
This procedure can be speeded up by selecting the CM-initialization mode
(OMDR:OMS1..0 = 10). If this selection is made, the access time to a single memory
location is reduced to 2.5 RCL-cycles. The complete initialization time for 32 IOM-2
channels is then reduced to 128
