there will be a fixed relationship between the instruction cycle
time of the DSP program and the AD74111, so a timer could be
used to accurately control the DAC updates. If a timer is not
available, the Multiframe-Sync (MFS) mode could be used to
generate a DFS pulse every 16 or 32 DCLKs, allowing the DSP
to accurately control the number of DCLKs between updates
using an autobuffering or DMA type technique. In all cases for
Slave mode operation, there should be 128 DCLKs (Normal
mode) or 256 DCLKs (Fast mode) between DAC updates. The
ADC operates in a similar manner; however, if the DSP does not
read an ADC result, this will appear only as a missed sample and
will not be audible. Slave mode is most suited to state-machine
type applications where the number of DCLKs and their
relationships to the other interface signals can be controlled.
