2.1.2 Example DLC Parallel Mode System
Figure 2-2 shows a typical DLC circuit (PLCC). The component values displayed are
recommended, although adjustment may be required in actual operation. The exam-
ple is shown wired for low-power standby mode. Typical M68HC11 MCU connections
are shown, but any host MCU that has appropriate inputs and outputs compatible with
DLC signals can be used.
