FM VCO (local oscillator) input.
This pin is selected with CW1 in the PLL instruction.
The signal input to this pin must be capacitor coupled.
Input is disabled in Backup mode, after a power on reset, and in the
PLL stopped state.
AM VCO (local oscillator) input.
This pin is selected and the band set with CW1 (b1, b0) in the PLL
instruction.

The signal input to this pin must be capacitor coupled.
Input is disabled in Backup mode, after a power on reset, and in the
PLL stopped state.
Sub-charge pump output and general-purpose input shared function
port.
The IOS2 instruction is used for switching between the sub-charge
pump output and general-purpose input functions.
When used as the sub-charge pump output :
The sub-charge pump output function is set up with the IOS2
instruction.
A high-speed locking circuit can be formed by using this pin in
conjunction with the main charge pump.
The sub-charge pump is controlled using the DZC instruction.

When used as a general-purpose input :
The general-purpose input function is set up with the IOS2
instruction.
Data is read from the port using the INR instruction.
This pin goes to the high-impedance state in Backup mode, after a
power on reset, and in the PLL stopped state.
