Enhanced Time Processing Unit (eTPU2)
type of event. However, when an HSR service thread is called (entry numbers 0 to 9), other events may
also have been recognized, and it is microcode responsibility to check them.
When HSR is 0, i.e., Host did not issue a Service Request to the channel, the other event conditions, the
input signal state and channel flags determine the Entry Point. Note that channel flag 1 does not influence
the encoding in this scheme.
