The WMM [EVEN/ODD] RAM CTRL registers prog_addr fields are used to define the start address
of the waveform. These fields should be set to 0 in order to store a full 16k point waveform. For the
multiple waveform mode, the number entered into these fields is the start location within the 2k x 64-
bit ODD/EVEN RAM element that the waveform is to be stored. One address location in this field
translates to eight waveform vector points because four points are stored at each address of the ODD
and EVEN RAM blocks.
The WMM [EVEN/ODD] RAM CTRL registers prog_burst fields sets the length of the stored
waveform, defined as the number of waveform points divided by eight, minus one. Every RAM
address in each of the ODD, EVEN, RAM A and RAM B memories corresponds to a 64-bit location.
Each location is divided into four 16-bit samples.
Figure 16 shows an example of how a 32 point vector is stored. In this example prog_addr is set to
0 and prog_burst = 3.
