SLES173–MARCH 2006
The PCM1850A/1851A 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 (PCM1850A)
and
I
2
C Serial Control Port for Mode Control (PCM1851A)
sections of this data sheet.
Table 6
lists the available mode control functions, along with their reset default conditions and associated register
index.
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].
