CH[15:0] — Encoded Host Sequence
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 function specified.
CH[15:0] — Encoded Type of Host Service
The host service request field selects the type of host service request for the time function selected on
a given channel. The meaning of the host service request bits depends 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 writing 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 request to the channel.
