ANALOG
- Software Mode (MODE = "High")
Software Mode functions are controlled by Mode Interface. When the 16-bit serial data is applied to the
MCKDEM, MDAFS1,MLDFS0 pins in the form of Fig4. Software Mode is accomplished. The higher 4bits
(MSB First Format-Bin) should be Mode Interface 4bit ID number, the middle 4bits are Address, and
according to the lower 8 bits(MSB First Format-Bin) can be adjusted to Data. When RSTB is low state,
Software Mode becomes default values. Digital Soft Attenuation (ATTL / ATTR) of Software Mode is
attenuated by the same degree that Soft Mute Control does. In case of no Software Mode function
needed, MDAFS1 should be "L", MCKDEM and MLDFS0 should be "H".
