L64733 Signal Descriptions
This section describes the L64733 signals.
Figure 5
shows the interface
diagram of the L64733. Names of signals that are active-LOW are
designated with an “n” suffix (for example, ERROROUTn). Names of
differential signals are designated with a “p” suffix for the noninverting
side (for example, QOUTp), and with an “n” suffix for the inverting side
(for example, QOUTn).
