2.2.2 Example DLC Serial Mode System
2-10
MOTOROLA
Figure 2-3 displays a typical DLC serial mode circuit (PLCC). The component values
displayed are recommended, although adjustment may be required in actual opera-
tion. The example is shown wired for low-power standby mode. Typical M68HC11
MCU connections are shown, but any host MCU that has appropriate inputs and out-
puts compatible with DLC signals can be used.
