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
