• Indicates the state of the unlocked state detection circuit.
• Indicates the value of the IF counter (20-bit binary counter).
• Data that reflects the LCTS bit in the serial input data. The LCT output data allows applications to verify the
pin state regardless of the I/O port mode (input or output). The data is latched at the point the circuit enters
data output mode (OUT mode).
