In Steps 3 and 4, you must specify an offset value and offset data. You can determine
the values of the offset address and offset data by examining the data records
specified in either the channel or PLL MIFs. Figure 10–6 shows a sample MIF.
For the sample data record in Figure 10–6, the length field specifies three data records.
The offset value is 0, as indicated by bits 10–0. The offset data are the three subsequent
entries. Example 10–5 performs a direct write in Streamer mode 1. This example
writes the sample MIF in Figure 10–6 into the Streamer module which writes this data
to logical channel 0.
