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.
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 non-zero states.
The CPU16 should monitor the host service request register until the TPU2 clears the
service request to %00 before any parameters are changed or a new service request
is issued to the channel.
