MODE CONTROL REGISTERS
User-Programmable Mode Control Functions
The PCM1850/1851 has several user-programmable functions which are accessed via control registers. The registers are
programmed using the serial control port which is discussed in the
SPI Serial Control Port for Mode Control (PCM1850)
and
I
2
C Serial Control Port for Mode Control (PCM1851)
sections of this data sheet. Table 6 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 7. Each register includes an index (or address) indicated by the IDX[6:0]
bits B[14:8].
