MODE CONTROL REGISTERS
User-Programmable Mode Controls
The DSD1794 includes a number of user-programmable functions which are accessed via mode control registers.
The registers are programmed using the serial control interface, discussed in the
SERIAL CONTROL INTERFACE
(I

C)
section of this data sheet. Table 2 lists the available mode-control functions, along with their default reset
conditions and associated register index.
