Functional Description
Refer to the
eTPU Reference Manual
for information regarding the functional description of the eTPU
module.

Initialization/Application Information
After initial power-on reset, the eTPU remains in an idle state (except when debug is asserted on power-on
reset—in this case, the microengines awaken in the halt state). In addition, initialize the SCM with the
eTPU application prior to configuring the eTPU.

HSR
[0:2]
Host service request. Used by the host core to request service to the channel
• HSR = 000: no host service request pending
• HSR
>
000: function-dependent host service request pending.
The HSR value turns to 000 automatically at the end of microengine service for that channel. The host must write
HSR
>
0 only when HSR = 0. Writing HSR = 000 withdraws a pending request if the scheduler has not started to
resolve the entry point, however after the scheduler starts resolving, do not abort the service thread.
