Bandwidth can be wasted during transfers in cut through mode. If the ingress port operates at a slower
rate than the egress port, the egress port receives idles whenever the ingress port has not yet received
data for transmission. However, during the transfer, the egress port cannot receive information from
ports other than the egress port. Therefore, when transferring data between ports of different
bandwidths, it is recommended that the slower port not operate in cut-through mode. Refer to the
TRANS_MODE bit in

“RapidIO Port x Control Independent Register” on page 321

for more

information on how to control cut-through mode.
