Control block/data
Function
• Data latched from the I/O port IO1 or IO2 pin states.
I/O port data
• These bits reflect the pin states regardless of the I/O port mode (input or output).
(1)
The data is latched at the point the circuit enters data output mode (OUT mode).
I2, I1
I1 ← The IO1 pin state
High : 1
I2 ← The IO2 pin state
Low : 0
PLL unlocked state • Indicates the state of the unlocked state detection circuit.
(2)
data
UL ← 0: When the PLL is unlocked.
UL
UL ← 1: When the PLL is locked or in the detection disabled mode.
IF counter
• Indicates the value of the IF counter (20-bit binary counter).
(3)
binary counter
C19 ← MSB of the binary counter
C19 to C0
C0 ← LSB of the binary counter
