Not applicable
Several MDIO register bits may be affected by Boolean functions. When a bit value is overridden through a Boolean
function, writes to that bit are ignored. The bit returns to its prior value once the override is removed.
Table 3−13. Control Register Bit Definitions (Register 0)
BIT(S)
NAME
Logically ORed with the inverse of the RSTN terminal.
15
Reset
1 = Global resets including FIFO clear
0 = Normal operation
1 = Enable loopback mode on all channels.
14
Loopback
0 = Disable loopback mode on all channels (default).
13
Speed selection (LSB)
Not applicable. Read returns a 1.
12
Auto-negotiation enable
Not applicable. Read returns a 0.
Logically ORed with the inversion of the ENABLE terminal.
11
Power down
1 = Power-down mode is enabled.
0 = Normal operation (default).
10
Isolate
Not applicable. Read returns a 0.
9
Restart auto-negotiation
Not applicable. Read returns a 0.
8
Duplex mode
Only full duplex is supported. Writes are ignored. Read returns a 1.
7
Collision test
Not applicable. Read returns a 0.
6
Speed selection (MSB)
Not applicable. Read returns a 1.
5:0
Reserved
Write as 0. Ignore on read.
† After reset, this bit is set to 1; it automatically sets itself back to 0 on the next MDC clock cycle.
Table 3−14. Status Register Bit Definitions (Register 1)
BIT(S)
NAME
15:9
Read returns all 0s.
8
Extended status
Read returns a 1, indicating extended status information is held in register 15.
7
Reserved
Read is ignored.
6:3
Various configurations
Read returns all 0s.
1 = Link is up
0 = Link is down
2
Link status
Latches low until read.
1
Jabber detect
Read returns a 0.
0
Extended capability
Read returns a 1, indicating extended register capability.
Registers 2 and 3 contain the identifier for the 10-Gbps ethernet XGXS device.
The identifier code is composed of bits 3−24 of the 25-bit organizationally unique identifier (OUI) assigned to Texas
Instruments by the IEEE. The 6-bit manufacturer model number is unique to the TLK3114SC device. The
manufacturer revision number denotes the current revision of the TLK3114SC device.
