17.18.2. Mode 1 Avalon-MM Direct Writes for Reconfiguration

This section describes mode 1 Avalon-MM direct writes for reconfiguration.

You specify this mode by writing a value of 2'b01 into bits 2 and 3 of the control and status register, as indicated in Streamer Module Registers. In this mode, you can write directly to transceiver PHY IP core registers to perform reconfiguration. Refer to “Direct Write Reconfiguration” for an example of an update using mode 1. In mode 1, you can selectively reconfigure portions of the transceiver PHY IP core. Unlike mode 0, mode 1 allows you to write only the data required for a reconfiguration.
