In serial control mode (SPB pin= “H”), the setting of DEM1-0 pins is ignored. The DEM[11:10] bits setting is
reflected to SRC1, the DEM[21:20] bits setting is reflected to SRC2 and the DEM[31:30] bits setting is reflected
to SRC3.
In serial control mode (SPB pin = “H”), the setting of IDIF2-0 pins is ignored. The IDIF[12:10] bits setting is
reflected to SRC1, the IDIF[22:20] bits setting is reflected to SRC2 and the IDIF[32:30] bits setting is reflected
to SRC3.
