MODE CONTROL REGISTERS
User-Programmable Mode Controls
The PCM1600 includes a number of user-programmable
functions which are accessed via control registers. The
registers are programmed using the Serial Control Interface
which was previously discussed in this data sheet. Table III
lists the available mode control functions, along with their
reset default conditions and associated register index.

Register Map
The mode control register map is shown in Table IV. Each
register includes a R/W bit, which determines whether a
register read (R/W =1) or write (R/W = 0) operation is
performed. Each register also includes an index (or address)
indicated by the IDX[6:0] bits.
Reserved Registers
Registers 0 and 12 are reserved for factory use. To ensure
proper operation, the user should not write or read these
registers.
