Crystal mode: crystal input
RC mode: pull-high resistor
PLL mode: connect 0.01µF capacitance to GND.
Connect a 0.01µF capacitor to GND and code option select PLL
mode when high oscillator is not used.
Crystal mode: crystal output
RC mode: instruction clock output
PLL mode: instruction clock output
Test signal import pin (must be connected to VDD)
Crystal mode: input pin for sub-oscillator. Connect to a 32.768kHz
RC mode: pull-high resistor
Crystal mode: connect to a 32.768kHz crystal.
Input pin with Schmitt Trigger. If this pin remains at logic low, the
controller will also remain in reset condition.
