NOTES: (1) N/A = not assigned. No operation even if setting any data. (2) RSV = reserved for test operation. It should be set “0” during regular operation.

MODE CONTROL REGISTERS

User-Programmable Mode Controls

The PCM1602 includes a number of user-programmable

functions that are accessed via control registers. The regis-

ters are programmed using the Serial Control Interface that

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 that determines whether a regis-

ter read (R/W = 1) or write (R/W = 0) operation is per-

formed. 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.
