bridge_ddrreg_sprt_8_118_p_0
This register describes the weight value of each QoS supported at the bridge. Each byte of this register must be greater than or equal to 3. Each transmitting bridge supports up to 16 QoS profiles. Each QoS is composed of priority and weight, however only the weight is programmable, therefore is part of the registers.
QoS data is composed of four registers, P0, P1, P2, and P3, each of which contains the weight of four profiles. Depending upon how many QoS profiles are enabled, the appropriate bits in the following registers are available.
