1. R = Read Only, LH = Latching High – cleared when read.
2. The default values are updated on completion of reset and reflect the status or change in status at that
3. The default value is determined by the default value of Register bit 0.12.
4. LSHR = Default value is derived from a single device input pin state or a group of device input pin states as
5. Default values are set by the hardware configuration PAUSE pin. The BGA15 package does not have a
1. R/W = Read/Write
2. In 10 Mbps operation, Register bit 18.13 = 1 cannot be used when Register bits 18.15:14 = “11” and in
3. SFD Frame Alignment is applicable to SMII and SS-SMII only.

0 = Auto-negotiation process is not complete
1 = Auto-negotiation process is complete
0 = No FIFO error occurred
1 = FIFO error occurred (overflow or underflow)
0 = Polarity is not reversed
1 = Polarity is reversed

During 100 Mbps operation, this bit is not valid
and may vary. Auto MDIX activity may increase
the variability.
This bit is not affected by Register bit 4.10.
The default for the BGA15 package is 0.
The register is cleared when the registers that
generated the error condition are read.
