8.4.11.1 State Transition #1 - Standby to Normal
Autonomous Operation: The PHY will automatically transition to Normal state upon POR completion.
Managed Operation: The PHY will transition to Normal state out of Standby if any of the following occurs:
- Energy detection, when energy is detected on the MDI
- Register access, enabling Autonomous operation by setting bit[6] in the AUTO_PHY Register 0x018B – Autonomous PHY Control Register
- Register access, forcing Normal state by setting bit[0] in the PWRM Register 0x018C – Power Mode Register
