36.4.2.2 Details of the SSD Measurement
This section describes in detail the steps introduced in Figure 36-12. Note that it describes only the
measurement process. The decision whether the stall position has been reached or another SM step is
required must be made by the controlling CPU depending from the measurement result. All control bits
are assumed to have their (inactive) reset values prior to entering the SSD measurement flow. The
following paragraphs relate to one complete BIS including the (optional) blanking phase followed by the
integration phase:
