Figure 1-5. 44-Lead PLCC Pin Assignments
NOTE
The 44-pin PLCC pin assignment diagram is for compatibility with the
MC68HC705C9A. However, if MC68HC705C9A devices are to be used in
the same socket, pin 3 should be tied to VDD.
For compatibility with MC68HC05C4A/C8A/C12A devices in 44-pin PLCC,
tie pins 17 and 18 together, and tie pins 39 and 40 together.
For compatibility with MC68HC705C8A 44-pin PLCC device, three sets of
pins should be tied together: pins 17 and 18, pins 39 and 40, and
pins 3, 4, and 44.
