MODE CONTROL REGISTERS
User-Programmable Mode Controls
The PCM1602A includes a number of user-programmable functions that are accessed via control registers. The
registers are programmed using the serial control interface that is previously discussed in this data sheet.
Table 3 lists the available mode control functions, along with their reset default conditions and associated register
index.
