Bits 15:9 – FALLSLP[6:0] Falling Slope

Sets the rate at which credits are reduced when transmitting. Each time the PHY transmits the number of bytes configured by this parameter, the credit count will be decremented by one, until the bottom limit is reached.

Bits 8:1 – RISESLP[7:0] Rising Slope

Sets the rate at which credits are increased when receiving or idle. The PHY will count the number of received bytes or 800 ms periods of idle time. When the receive/idle byte count reaches the value in this parameter, the receive/idle byte count will be reset to 0 and the credit count will be incremented by one, until the top limit is reached.
