Resume Level Low
These bits specify the buffer usage level during times when 2 or 3 ports are
active.
Each buffer is 128 bytes.
Note:
Resume Level High
These bits specify the buffer usage level during times when 0 or 1 ports are
active.
Each buffer is 128 bytes.
Note:
Buffer Manager Flow Control Resume Level Register (BM_FC_RESUME_LVL)
This register configures the buffer usage level when a Pause frame with a pause value of 1 is sent.
A port is “active” when 36 buffers are in use for that port.
