1. R/W = Read/Write
2. The default value of bit 19.13 is determined by pin MF1.
3. If auto-negotiation is disabled, the default value of bit 19.8 is determined by pin CFG1. If auto-neg is enabled, the default
4. The default value of bit 19.4 is determined by pin MF2 Operation.
5. The default value of bit 19.3 is determined by pin MF3 Operation.
6. If auto-negotiation is disabled, default value of bit 19.2 is determined by pin MF4. If auto-negotiation is enabled, default value
1. RO = Read Only
2. Bits 20.12 and 20.11 reflect the current operating mode of the LXT970A Transceiver.
