126 M8190A User’s Guide
Examples:
One segment with 257 or more sample vectors (big segment)
One segment with 129 vectors and a loop count of 2 (Loop count multiplies the
segment length)
Two segments with 126 and 131 vectors. (Multiple small segments are combined
to meet the requirement)
One segment of 5 vectors and one big segment. (One or multiple small segments
which don’t meet the linear playtime requirement by themselves, must be located
in the memory in front of the next big segment)
Any small segment with a conditional advancement causes the linear playtime
requirement to be met automatically. The advancement event to exit the segment
is delayed internally until the linear playtime condition is met. A status register
signals any linear playtime violation.
Any small segment with an advancement mode set to repeated or single causes
the linear playtime requirement to be met automatically. The advancement event is
delayed internally until the linear playtime condition is met. A status register
signals any linear playtime violation.

Figure 3-35: Linear playtime requirement
For the given example sequence the linear play time requirement is met. Segment A is a
segment with a play time that is bigger than 256 vectors. Due to its loop count,
segment B is also bigger than 256 vectors. Segment C and D are placed next to each
other and the resulting length is 260 vectors. The small segment E is placed in front of a
big segment.
