15.7. Initializing the Physical Layer
The physical layer should be configured to the desired mode prior to setting the enable bit PHYEN (PHYCN.7). The
following procedure should be used to initialize the physical layer:
Step 1: If auto-negotiation is used, implement the synchronization procedure in Section 15.2 on page 88.
Step 2: Disable the physical layer by writing 0x00 to the PHYCN register.
Step 3: Configure Desired Options using the PHYCN and PHYCF registers:
1.Specify the Duplex Mode or enable Auto-Negotiation.
2.Enable or Disable Loopback Mode.
3.Disable the transmitter power save mode (TXPWR = 0x80).
4.Enable the desired functions such as Receiver Smart Squelch, Automatic Polarity Correction, Link
Integrity, Jabber Protection, and PAUSE packet capability advertisement.
5.If Automatic Polarity Correction is disabled, manually set the desired polarity.
Step 4: Enable the physical layer:
1.Enable the physical layer (PHYEN = 1).
2.Wait for the physical layer to power up. See Physical Layer Startup Time in Table 22 on page 93.
3.Enable the transmitter and receiver (TXEN = 1 and RXEN = 1).
Step 5: Wait for auto-negotiation to complete. If auto-negotiation is not enabled, software may wait for a valid
link or go directly to MAC Initialization.
Step 6: Enable the desired Activity, Link, or Activity/Link LEDs using the Register 15, “IOPWR: Port Input/
Step 7: Initialize the MAC to the same duplex mode reported by the physical layer in the PHYCN register.
Note: Step 6 and Step 7 are repeated in the reset initialization procedure. Software only needs to perform these steps once.
