Channel 0 is given the lowest
priority.
When channel 1 is given the
lowest priority, the priority
of channel 0, which was
above channel 1, is also shifted
simultaneously.
When channel 2 receives the
lowest priority, the priorities
of channel 0 and 1, which
were above channel 2, are also
shifted simultaneously. Immedi-
ately thereafter, if there is a transfer
request for channel 1 only, channel
1 is given the lowest priority,
and the priorities of channels 3
and 0 are simultaneously
shifted down.
No change in priority.
