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.
