An STOV interrupt is not generated if all stimulating STI interrupts are acknowledged.
An STIxy must be acknowledged by setting the ACKxy bit in the ASTI register until two
BCL clocks (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 in
