Description
This along with port control 6, bits [7:0] form a 12-bit
field to determine how many “32Kbps” low priority
blocks can be transmitted. (In a unit of 4K bytes in a
one second period.)
This along with port control 5, bits [7:0] form a 12-bit
field to determine how many “32Kbps” high priority
blocks can be transmitted. (In unit of 4K bytes in a
one second period.)
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
