Table 7. DAC system clock example (DAC Quad Speed Mode @Manual Setting Mode)
2. Auto Setting Mode (ACKS bit = “1”)
When the ACKS bit = “1”, DAC is in Auto Setting Mode and the sampling speed is selected automatically by the ratio
MCLKA/LRCKA as shown in the Table 8. and the internal master clock is set to the appropriate frequency (Table 9). In
this mode, the setting of DFS1-0 bits are ignored.
