MODE CONTROL REGISTERS
User-Programmable Mode Controls
The DSD1792 includes a number of user-programmable functions which are accessed via mode control registers. The
registers are programmed using the serial control interface, which was previously discussed in this data sheet. Table 2 lists
the available mode-control functions, along with their default reset conditions and associated register index.
