Zarlink Semiconductor Inc.
12.3.6.55
RPRIORITY – User Define Range Priority
I2C Address h0D5, CPU Address: 59e
Accessed by CPU, serial interface and I2C (R/W)
RLOW and RHIGH form a range for logical ports to be classified with priority specified in RPRIORITY.
12.3.6.56
CPUQOSC1,2,3
CPU Address: 5a0, 5a1, 5a2
Accessed by CPU and serial interface (R/W)
C - CPUQOSC1 – CPU BYTE_C1 (CPU Address 5A0)
B - CPUQOSC2 – CPU BYTE_C2 (CPU Address 5A1)
A - CPUQOSC3 – CPU BYTE_C3 (CPU Address 5A2)
Represents values A-C for a CPU port. The values A-C are per-queue byte thresholds for random early drop.
QOSC3 represents A, and QOSC1 represents C. Granularity: 256 bytes

Bits [7]:
Half duplex flow control feature
0 = Half duplex flow control always enable
1 = Half duplex flow control by negotiation
Bits [6]:
Link partner reset auto-negotiate disable
Bits [5]:
Disable jabber detection. This is for HomePNA applications or any serial
operation slower than 10 Mbps.
0 = Enable
1 = Disable
Bit [4:0]:
Vendor specified link status register address (null value means don’t use it)
(Default 00). This is used if the Linkup bit position in the PHY is non-
standard.
