Description
1 = If bit 6 is also ‘1’ this will enable receive rate control
for this port on low priority packets at the low priority
rate. If bit 5 is also ‘1’, this will enable receive rate
control on high priority packets at the high priority rate.
0 = receive rate control will be based on the low priority
rate for all packets on this port.
1 = enable port’s low priority receive rate control feature.
0 = disable port’s low priority receive rate control.
1 = if bit 7 is also ‘1’ this will enable the port’s high
priority receive rate control feature. If bit 7 is a ‘0’ and
bit 6 is a ‘1’, all receive packets on this port will be rate
controlled at the low priority rate.
0 = disable port’s high priority receive rate control feature.
1 = flow control may be asserted if the port’s low priority
receive rate is exceeded.
0 = flow control is not asserted if the port’s low priority
receive rate is exceeded.
1 = flow control may be asserted if the port’s high
priority receive rate is exceeded. (To use this, differential
receive rate control must be on.)
0 = flow control is not asserted if the port’s high
priority receive rate is exceeded.
1 = will do transmit rate control on both high and low
priority packets based on the rate counters defined by
the high and low priority packets respectively.
0 = will do transmit rate control on any packets
The rate counters defined in low priority will be used.
1 = enable the port’s low priority transmit rate control
feature.
0 = disable the port’s low priority transmit rate control
feature.
1 = enable the port’s high priority transmit rate control
feature.
0 = disable the port’s high priority transmit rate control
feature.
Description
1 = disable auto-negotiation, speed and duplex are
decided by bit 6 and 5 of the same register.
0 = auto-negotiation is on.
1 = forced 100BT if AN is disabled (bit 7).
0 = forced 10BT if AN is disabled (bit 7).
