LC8903, 8903Q

Microprocessor Interface

The microprocessor interface is used for specifying the data input pin, for setting the output data format, and for

specifying subcode output, system stop, and analog source mode. The figure shows the interface I/O formats.

Microprocessor Interface Formats

Address

The bits B0 to A3 in the format figure are the address. There are two addresses allocated to the LC8903/Q, one for input

and one for output. The microprocessor must specify the input address to input data and the output address to output data.

Microprocessor Interface Input

1. Input pin and validity output settings

The DIN1 to DIN4 data input pins have built-in amplifiers and can accept signals with levels of about 400 mVp-p.

DIN5 is a special-purpose input pin for optical input.

The data input system multiplexer is controlled by inputs from the microprocessor interface. The table shows the

relationship between the code in bits I5 to I13 in the microprocessor interface format and the data demodulation

outputs DOUT1 and V/DOUT2.

V is output from the V/DOUT2 pin.
