3.2 System Block Diagram and Pin Assignment Diagrams
3-2
Figure 3-1 is a functional diagram of the MCU. Although diagram blocks represent the
relative size of the physical modules, there is not a one-to-one correspondence be-
tween location and size of blocks in the diagram and location and size of integrated-
circuit modules. Figure 3-2 shows the pin assignments of the 132-pin plastic surface-
mount package. Figure 3-3 shows the pin assignments of the 144-pin plastic surface-
mount package. Refer to APPENDIX B MECHANICAL DATA AND ORDERING IN-
FORMATION for package dimensions. All pin functions and signal names are shown
in this drawing. Refer to subsequent paragraphs in this section for pin and signal de-
scriptions.
