Debug Support
32.10.3 Development Status Register (DS)
The read-only DS register shows the status of various conditions that impact development support.
All status bits are dynamic and do not require clearing.
The DS register dynamically tracks the debug condition status even when several of them are
simultaneously asserted. For instance, if EVTI and an internal client debug request (this could be
any of the other on chip modules) are asserted at the same time, the eTPU engine will enter debug
mode and EDM will assert the bits EBP[EVTI] and CBP (internal client). Then, if CBR is asserted
the EBP bit will be cleared but the CBP bit will continue to be active since the internal client debug
request signal is still active.

A request to delay the processor while the eTPU is in TST will be recognized after eTPU exits TST and before the
first instruction of the thread.
One microcycle of the eTPU corresponds to two system clocks. And since the eTPU events are evaluated on every
single clock, one single microcycle may generate up to two snapshots.
If both registers are programmed to stall while the queue gets full, only the CDC can generate an overrun message.
