Data Format Control. SOFT MUTE Soft Mute function can be controlled by MUTE (pin 25) SOFTWARE MODE (MODE = H) PCM1716’s special functions at software mode is shown in Table VI. These functions are controlled using a ML, MC, MD serial control signal.

Selectable Functions and Default. PROGRAM REGISTER BIT MAPPING PCM1716’s special functions are controlled using four pro- gram registers which are 16 bits long. These registers are all loaded using MD. After the 16 data bits are clocked in, ML is used to latch in the data to the appropriate register. Table VII shows the complete mapping of the four registers and Figure 7 illustrates the serial interface timing.
