Enhanced Time Processing Unit (eTPU)
20.6.2.3.8 eTPU Channel Service Status Register (ETPU_CSSR)
ETPU_CSSR holds the current channel service status on whether it is being serviced or not. Only
one bit may be asserted in this register at a given time. When no channel is being serviced the
register read value is 0x00000000. ETPU_CSSR is a read-only register. The register can be read
during normal eTPU operation for monitoring the scheduler activity. For more information on
channels being serviced, refer to the eTPU User’s Manual.

The pending service status bit for a channel is set when a service
request is pending, even if the channel is disabled (CPRn = 0).
The ETPU_CSSR is not an absolute indication of channel status. If
more than one source is requesting service, the asserted status bit only
indicates that one of the requests has been granted.
Channel service status does not always reflect decoding of the CHAN
register, since the CHAN register can be changed by the service thread
microcode.
