°AW and AR channels: One latency cycle.
°W channel when upsizing: One latency cycle (for each cycle in which packing completes), with no bubble cycles on the SI-side (narrow) interface.
°R channel when upsizing: One latency cycle.
°B channel: no latency.
°R channel when downsizing: no latency (for each cycle in which packing completes), with no bubble cycles on the MI-side (narrow) interface.
°W channel when downsizing: no latency.
