ming to access the registers. The commands are input to the 77010 via the DPI-4 transmit path. The PHY register commands are decoded by the
77010 and executed using the Utility bus.

The Receive DPI Clock (DRxCLK) is a continuous clock generated from SYSCLK and is twice the frequency of RCLK. The Receive Start of Cell
There is no flow control in the receive DPI path. It is assumed that the receiving device can accept the incoming cell.
DRxFRM and DRxDATA[3:0] are sampled on the rising edge of DRxCLK.
The Utility bus is used for accessing the internal PHY registers. An 8-bit read or write command is implemented via instream (in-band) program-
Figure 10 shows the Utility bus interface.
