DA6116.010

5 October, 2017

On the PCB board the same DATA and CCLK lines can be routed to every MAS6116 chip. If the XCS-pin is not

active (low), DATA pin of that chip is in high-impedance state. This allows using a simple PCB board for multi-

channel audio systems.

The device may be operated with a constant CCLK signal (see figure 1 and 2 examples), or the CCLK signal may

be stopped between commands (see figure 3). The CCLK signal may be stopped in either high or low state. If the

CCLK is stopped between commands, care must be taken to ensure that the chip receives exactly 16 rising clock

edges while XCS is low and that there are no timing violations. See figure 3 signal example of Normal write to both

channels (command 48h=%0100 1000,

don’t care bits 0) with written byte E0h=%1110 0000 and having the CCLK

is stopped between commands.

Figure 3. Normal write to both channels (command 48h=%0100 10

00, don’t care bits 0) with written byte

E0h=%1110 0000 and the CCLK is stopped between commands.

The write command 48h in figure 3 is ambiguous with command CBh in figure 1 since their only difference is

selecting don’t care bits 0 or 1 respectively.
