IF counter control data
IFS
This data must be set 1 in normal mode.
Though if this value is set to zero, the system enters input sensitivity degradation mode,
and the sensitivity is reduced to 10 to 30 mVrms.

These values must all be set to 0.
These test data are set to 0 automatically after the power-on reset.

I/O port data
I2, I1
Latched from the pin states of the IO1 and IO2 I/O ports.
These values follow the pin states regardless of the input or output setting.
Bits I2, I1 reflect the data latched into each input port when the device changes to OUT Mode.
I1
←
IO1 pin state
High: 1
I2
←
IO2 pin state
Low: 0
Latched from the state of the unlock detection circuit.
UL
←
0: Unlocked
UL
←
1: Locked or detection stopped mode
Latched from the value of the IF counter (20-bit binary counter).
C19
←
MSB of the binary counter
C0
←
LSB of the binary counter
PLL unlock data
