A.3 RC Oscillator Connections
Technical Data
NOTE:
For greater cost reduction, the RC oscillator mask option allows the
configuration shown in
the RC components as close as possible to the pins for startup
stabilization and to minimize output distortion.
The optional internal resistor is not recommended for configurations that
use the RC oscillator connections as shown in
configurations, the oscillator internal resistor (OSCRES) bit of the mask
option register should be programmed to a logic 0.
