MODE CONTROL REGISTERS
User-Programmable Mode Controls
The DSD1793 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 3 lists the available mode-control functions, along with their default reset conditions and associated register
index.
