Function
Initialize M66238 internal status.
Transfer serial data when CS=“L”.
Synchronize 32-bit serial data from MCU with SCK, and enter.
Enter a sync clock for writing 32-bit serial data.
Used by connecting crystal oscillator between XIN and XOUT. When using an
external clock signal, connect the clock oscillator to XIN pin and open XOUT pin.
Trigger input for clock sync.
Output an inverted CKO signal.
CKO outputs a clock synchronized with a trigger signal and PLLO outputs a PLL
oscillator clock as it is.
Output a one-shot pulse synchronized with a CKO signal.
Connect a low pass filter to charge pump output.
Low pass filter input pin.
Connect a load resistor for VCO circuit operation between RV and GND.
Shipping test pin. Connect to GND when use.
