2.3
PLL reference counter setting
The PLL reference counter generates phase comparison frequency0.
It consists of 9-bit reference counter. The divide factor can be set in the range 4 to 511 by sending
any data to the reference counter.

Auto-tuning reference counter setting
The TB32301AFL has an automatic tuning system to correct the fluctuation of center frequency in
FM detector, which is caused by, for example, temperature change. To generate a reference clock to
correct the fluctuation, set the divide factor of auto-tuning reference counter to the value to obtain
200-kHz frequency, according to external reference clock frequency.
The auto-tuning reference counter consists of 8 bits.
The divide factor can be set in the range 6 to 255 by sending any data to the reference counter.
