Note:
The Digital Reset (DIGITAL_RST) bit will cause the EEPROM Loader to reload the configuration strap val-
ues into the PHY registers and to reset all other PHY registers to their default values. An EEPROM RELOAD
command via the EEPROM Command Register (E2P_CMD) also has the same effect.
Control and Status Registers
Table 9-13 provides a list of supported registers. Register details, including bit definitions, are provided in the following
subsections.
Unless otherwise specified, reserved fields must be written with zeros if the register is written.
