17.18.1. Mode 0 Streaming a MIF for Reconfiguration

In mode 0, you can stream the contents of a MIF containing the reconfiguration data to the transceiver PHY IP core instance.

You specify this mode by writing a value of 2'b00 into bits 2 and 3 of the control and status register, as indicated in Streamer Module Registers. Mode 0 simplifies the reconfiguration process because all reconfiguration data is stored in the MIF, which is streamed to the transceiver PHY IP in a single step.

The MIF can change PLL settings, reference clock inputs, or the TX PLL selection. After the MIF streaming update is complete, all transceiver PHY IP core settings reflect the value specified by the MIF. Refer to Streamer-Based Reconfiguration for an example of a MIF update.
