Description
This along with port control 10, bits [3:0] form a 12-bit
field to determine how many “32Kbps” high priority
blocks can be received. (In a unit of 4K bytes in a one
second period.)
Description
This along with port control 10, bits [7:4] form a 12-bit
field to determine how many “32Kbps” low priority
blocks can be received. (In a unit of 4K bytes in a one
second period.)
Description
This along with port control 9, bits [7:0] form a 12-bit
field to determine how many “32Kbps” low priority
blocks can be received. (In a unit of 4K bytes in a one
second period.)
This along with port control 8, bits [7:0] form a 12-bit
field to determine how many “32Kbps” high priority
blocks can be received. (In a unit of 4K bytes in a one
second period.)
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.
