Name:
Access Type:
Writing to this register starts the shift register that controls the serial connection to the PHY. On each shift cycle the MDIO
pin becomes equal to the MSB of the shift register and LSB of the shift register becomes equal to the value of the MDIO
pin. When the shifting is complete an interrupt is generated and the IDLE field is set in the Network Status register.
When read, gives current shifted value.
• DATA
For a write operation this is written with the data to be written to the PHY. After a read operation this contains the data read
from the PHY.
• CODE
Must be written to 10 in accordance with IEEE standard 802.3. Reads as written.
• REGA
Register address. Specifies the register in the PHY to access.
• PHYA
PHY address. Normally is 0.
• RW
Read/Write Operation. 10 is read. 01 is write. Any other value is an invalid PHY management frame.
• HIGH
Must be written with 1 to make a valid PHY management frame. Conforms with IEEE standard 802.3.
• LOW
Must be written with 0 to make a valid PHY management frame. Conforms with IEEE standard 802.3.
