USER’S MANUAL
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.
The following paragraphs highlight capabilities of each of the microcontroller modules.
