3.2.4 Status Flags Panel
The TLV320AIC3256 status flags can be monitored in the Status Flags panel ( Figure 7 ) which is located
below the Panel Selection Tree. Pressing the POLL button continuously reads all the registers relevant to
each flag and updates those flags accordingly. The rate at which the registers are read can be modified by
changing the value in the Polling Interval numeric control. Note that a smaller interval reduces
responsiveness of other controls, especially volume sliders, due to bandwidth limitations. By default, the
polling interval is 200 ms and can be set to a minimum of 20 ms. The Sticky Flags tab contains indicators
whose corresponding register contents clear every time a read is performed to that register. To read all
the sticky flags, click the Read Sticky Flags button.
