C.5 RC Oscillator Connections (No External Resistor)

For maximum cost reduction, the RC oscillator mask connections shown

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 MC68HSR705J1A, an
internal resistor is selected which yields typical internal oscillator
frequencies as shown in
device is different than the resistance of the selectable internal resistor
on the MC68HC705J1A and the MC68HSC705J1A devices.
NOTE:
This option is not available on the ROM version of this device
(MC68HC05J1A).
