Appendix A. MC68HRC705KJ1
A.1 Introduction
This appendix introduces the MC68HRC705KJ1, a resistor-capacitor (RC)
oscillator mask option version of the MC68HC705KJ1. All of the information in
MC68HC705KJ1 Technical Data applies to the MC68HRC705KJ1 with the
exceptions given in this appendix.
A.2 RC Oscillator Connections
For greater cost reduction, the RC oscillator mask option allows the configuration
shown in Figure A-1 to drive the on-chip oscillator. Mount the RC components as
close as possible to the pins for startup stabilization and to minimize output
distortion.
Figure A-1. RC Oscillator Connections
NOTE:
The optional internal resistor is not recommended for configurations that use the
RC oscillator connections as shown in Figure A-1. For such configurations, the
oscillator internal resistor (OSCRES) bit of the mask option register should be
programmed to a logic 0.
