Compared to example 5 in example 7 a third STOVxy
generated additionally for both STIxy
A STOV interrupt is not generated if all stimulating STI interrupts are acknowledged.
A STIxy must be acknowledged by setting the ACKxy bit in the ASTI register two BCL
clock (for DPS=’0’) or one BCL clocks (for DPS=’1’) before the time slot which is selected
for the appropriate STIxy. The interrupt structure of the synchronous transfer is shown
