Note: Setting the data demodulation input code to one of the XSYS settings switches the system clock from the VCO to the crystal oscillator and sets
the LC8902/Q to analog source mode. Selecting one of the input pins once again sets the LC8902/Q to digital source mode and PLL operation.
2. Data output mode setting
There are two data output modes: 16-bit MSB first and 20-bit MSB first. These are selected by the bit I14 code.
3. System stop
The operation of both the VCO and the crystal oscillator can be stopped, thus stopping the whole LC8902/Q system,
by setting the bit I4 code as shown in the table.
The values of the bits I4 to I14 are all initialized to low immediately after the XMODE pin goes from low to high.
Since bits I0 to I3 and I15 are not used, their initial values are undefined.
Microcomputer Interface Output
Bits D0 to D15 in the microcomputer interface output format have the following meanings.
Interpretation of the D1 and D2 bits
Note: 1. The “#1” value indicates either a PLL lock error or analog source mode. In these states the data is cleared and bits D0 and D3 to D15 are all set to low.
2. D1 and D2 are in the “#1” state in the initial values of the codes immediately after the XMODE pin goes from low to high. All other codes are set to low.
3. The interval between one microcomputer data read out operation and the next must be 6 ms or longer.

Function
D0
Invalid bit. Always output as a low level.
