• 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 IO1 and IO2 I/O ports.
• These values follow the pin states regardless of the input or output setting.
• Data is latched at the point where the circuit enters data output mode (OUT mode).
• 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.
