• This data should be set to 1 during normal operation.
• Note that if this value is set to zero the system enters input sensitivity degradation mode,
• LSI test data
These test data are set to 0 automatically after the power-on reset.
Don’t care. This data must be set to 0.
• Latched from the pin states of the LCTR/I1 input port (L/I1 bit is set to 0)
• Latched from the state of the unlock detection circuit.
• Latched from the value of the IF counter (20-bit binary counter).
and the sensitivity is reduced to 10 to 30 mV rms.
