Figure 1-7. 44-Lead PLCC Pin Assignments
NOTE
The above 44-pin PLCC pin assignment diagram is for compatibility with
MC68HC05C9A. To allow compatibility with the 44-pin PLCC
MC68HC05C12A, pin17 and pin18 must be tied together and pin 39 and pin
40 also must be tied together.
To allow compatibility with MC68HC705C8A, pin 3 and pin 4 also should be
tied together.
