Channel 2 becomes lowest-
priority.
The priority of channels 0 and 1,
which were higher than channel 2,
are also shifted. If immediately
after there is a request to transfer
channel 1 only, channel 1 becomes
lowest-priority and the priority of
channels 0 and 3, which were
higher than channel 1, is also
shifted.
Channel 0 becomes lowest-
priority.
Channel 0 becomes lowest-
priority.
The priority of channel 0, which
was higher than channel 3, is also
shifted.
Priority order does not change.
