A.3 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.
