SECTION 3OVERVIEW

This section contains information about the entire modular microcontroller. It lists the

features of each module, shows device functional divisions and pin assignments, sum-

marizes signal and pin functions, discusses the intermodule bus, and provides system

memory maps. Timing and electrical specifications for the entire microcontroller and

for individual modules are provided in APPENDIX A ELECTRICAL CHARACTERIS-

TICS. Comprehensive module register descriptions and memory maps are provided

in APPENDIX D REGISTER SUMMARY.
