R/W
This register along with the next register determines
how many “64 byte blocks” of packet data allowed on
an input port in a preset period. The period is 50ms
for 100BT or 500ms for 10BT. The default is 1%.

This register along with the previous register
determines how many “64 byte blocks” of packet data
are allowed on an input port in a preset period. The
period is 67ms for 100BT or 500ms for 10BT. The
default is 1%.
0x63
Note: Rate: 148,800 frames/sec * 67 ms/interval * 1% = 99 frames/interval (approx.) = 0x63
