3.3.3. QoS access control register

A 1 in any bit of this register indicates that the SI corresponding to the bit position is permitted to use the reserved slots of the connected combined acceptance capability of the slaves.

The maximum value that you can write to this register is:

(2^<total number of SIs>) -1


If you attempt to write a value containing 1s in positions that do not correspond to SIs, then these bits are ignored and are not set in the register.

Changes to these values occur on the first possible arbitration time after they are written.
