1.6.2.3 2-Pin Resistor-Capacitor (RC) Combination
MC68HC05K0 • MC68HC05K1 — Rev. 2.0
To use the resonator-driven oscillator, select the crystal/ceramic
resonator mask option when ordering the MCU. The crystal/ceramic
resonator mask option connects an internal 2-M startup resistor
between OSC1 and OSC2.
For maximum cost reduction, use the 2-pin RC oscillator configuration
shown in
signal on OSC1 is a triangular-type wave. The optimum frequency for
the 2-pin oscillator configuration is 2 MHz.
To use the 2-pin RC oscillator configuration, select the 2-pin RC
oscillator mask option when ordering the MCU.
