Description
Reserved
The value read from this bit is indeterminate. Do not set this bit.
Phase Segment 2
This phase is used to compensate for phase edge errors. This
segment can be shortened by the re-synchronization jump width.
Phasse segment 2 is the maximum of Phase segment1 and the
Information Processing Time (= 2TQ).
Phase Segment 1
This phase is used to compensate for phase edge errors. This
segment can be lengthened by the re-synchronization jump width.
Sample Type
0 - once, at the sample point.
1 - three times, the threefold sampling of the bus is the sample
point and twice over a distance of a 1/2 period of the Tscl. The
result corresponds to the majority decision of the three values.
