CS4234
As can be seen from Figure 22, setting ‘100’ of the DAC5 Source[2:0] bits configures the DAC5 path to
use the mask bits to determine which signals are routed into the DAC5 path. The CS4234 is designed to
make any one of the slots of both the SDINx pins available to the 5
th
DAC Input Advisory block, where the
mask bits for the DAC5 path are located. The configuration of the mask bits is shown in Table 6 and
Table 7. In order to unmask a slot from the DAC5 path, a ‘0’ must be written to the appropriate bit within
the appropriate mask register.
