PIN DESCRIPTIONS
The MC68HC11D3 is available packaged as a 40-pin dual in-line package (DIP), a 44-
pin plastic leaded chip carrier (PLCC), or a 44-pin quad flat pack (QFP). Most pins on
this MCU serve two or more functions, as described in the following paragraphs. Refer
to Figure 2-1 and Figure 2-2, which shows the MC68HC11D3 pin assignments.
