The general equation is:

sendSlopeValue=((100 - AV percentage) / 100) x 8192

In this example, dedicating up to 75% of the total bandwidth to the AV traffic, obtain:

sendSlopeValue=((100 - 75) / 100) x 8192 = 2048

The calculated value for the sendSlopeValue should be written directly to the TX Arbiter Idle Slope Control Register. This provides a per-byte decrement value when relating this to AV Ethernet frame transmission.
