The host sequence field selects the mode of operation for the time function selected
on a given channel. The meaning of the host sequence bits depends on the time func-

CH[15:0] — Encoded Type of Host Service
The host service request field selects the type of host service request for the time func-
tion selected on a given channel. The meaning of the host service request bits de-
pends on the time function specified.
A host service request field cleared to %00 signals the host that service is completed
by the microengine on that channel. The host can request service on a channel by writ-
ing the corresponding host service request field to one of three nonzero states. The
CPU should monitor the host service request register until the TPU clears the service
request to %00 before the CPU changes any parameters or issues a new service re-
quest to the channel.
