mode control registers
user-programmable mode controls
The DSD1702 includes a number of user programmable functions that are accessed via control registers. The
registers are programmed using the serial control Interface as previously discussed in this data sheet. Table
2 lists the available mode control functions, along with their reset default conditions and associated register
index.
