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 0b00 signals the host that service is completed by the mi-
croengine 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 CPU must monitor the host service request
register until the TPU3 clears the service request to 0b00 before any parameters are changed or a new
service request is issued to the channel.
