3.3.2. QoS tidemark register

You can program this with the number of outstanding transactions that are permitted before the QoS scheme becomes active.

If a value is written to this register that is larger than the combined acceptance capability of the attached slave, then the QoS scheme never becomes active for this MI. If a value of 0 is written to this register, then the QoS scheme is turned off for this MI. This behavior ensures that it is impossible to block all transactions completely by accidental mis-programming.
