Description
This is used to program the QoS (Quality of Service). Tidemark is the maximum allowed number of transactions initiated but not completed, after which next transactions will be limited to certain masters. Access control sets which masters have this privilege. For more info, see CoreLink™ NIC-301 r1p2.
Maximum value for tidemark is 7. Maximum value for access control is 127 (1 bit for each slave interface).
