A.4 RC Oscillator Connections (No External Resistor)
For maximum cost reduction, the RC oscillator mask connections shown in
oscillator to be driven with no external components. This can be accomplished by programming the
oscillator internal resistor (OSCRES) bit in the mask option register to a logic 1. When programming the
OSCRES bit for the MC68HRC705KJ1, an internal resistor is selected which yields typical internal
oscillator frequencies as shown in
resistance of the selectable internal resistor on the MC68HC705KJ1 and the MC68HRC705KJ1 devices.
