(1) Programmable
divider data
P0 to P15
Data that sets the divisor of the programmable divider.
A binary value in which P15 is the MSB. The LSB changes depending on
DVS and SNS. (*: don’t care)

* PLL INHIBIT
Note *: PLL INHIBIT
The programmable divider block and the IF counter block are stopped, the FMIN, AMIN,
and IFIN pins are set to the pull-down state (ground), and the charge pump goes to the
high impedance state.

Crystal resonator selection
XS=0: 4.5MHz
XS=1: 7.2MHz
The 7.2MHz frequency is selected after the power-on reset.
