Digital Interface Specification (reference)
3-wire bus (For communication line)
Access to the LV24030 is done through the 3-wire bus.
CLOCK

NR_W
Write/read control
DATA
Data is written into LC24030 when the bidirectional communication line NR_W is H and is read from LV24030 when NR_W is L.
LV24030 has a function to notify occurrence of interruption by means of change in the DATA line.
If interruption is to be made, it is essential that the controller supports interruption by change of the DATA line.
When the timing necessary for frequency measurement cannot be generated from the controller, it is necessary to input
the external clock (oscillator or 32kHz crystal) to the CLK_IN pin of LV24030.
