I have about the 32Ksps waveform buffer spare cells. Per the user guide..
Every sample set is separated in the memory from the adjacent one by the use of spare cells, which do not contain
any sample data, as shown in Figure 49. In this way, every eighth 32-bit memory location in the buffer is reserved as a spare cell. If the seventh channel is disabled, with the WF_IN_EN bit in the WFB_CFG register equal to 0, the IN sample locations are treated as spare cells as well.
When I burst read the buffer at 32ksps the spare cells contain data and are not blank, is this correct or should the spare cells read zero or 0xFFFFFFFF?
