1. LSHR = Default value is derived from a single device input pin state or a group of device input pin states as
2. Default values for Register bits 27.11:10 are determined by the TxSLEW pins.
3. Default value for Register bit 27.9 is determined by the AMDIX_EN pin.
4. Default value for Register bit 27.8 is determined by the MDIX pin. BGA15 does not support the MDIX
5. R/W = Read/Write, R = Read Only, LH = Latching High – cleared when read.
