3. Pin setting/serial setting mode
The setting modes of this LSI can be broadly classified into two: the pin setting mode and the serial setting
mode. Switching between these modes is achieved by the SCMODE pin.
The pins of this LSI that become not significant in serial setting mode are listed below:
DIVCODE pin, CHNUM pin, DIFM0 pin, DIFM1 pin
In the serial setting mode, these pins can be set by serial setting. The rated values of the parameters which
cannot be changed in pin setting mode (they can be changed in serial setting mode) are given below.

CRCCK is valid only when crc_flag on Source_Info is set to "1", and when the CRC check is performed, the
CRC errors affect the output data.
(1) Pin setting mode
In the pin setting mode (SCMODE = low), this LSI enables the various LSI operations to be changed by the
DIVCODE pin, CHNUM pin, DIFM0 pin and DIFM1 pin.
(2) Serial setting mode
In serial setting mode (SCMODE = high), this LSI enables the various LSI operations to be changed by the
serial interface.
