Option 6 (Controlled Update, Same Data,

Software LDAC, and Multiple Channel)

Option 6 allows immediate and simultaneous

update of multiple DAC_CHn registers identi-

fied by MULTI_INPUT_SEL_0(MI_SEL_CH_n) and

SW_LDAC_EN_0(SLD_EN_CH_n) bitfields with the same data.

Data is contained in MULTI_INPUT_CH register and is initiated

through the software LDAC.

Option 6 is ideal for multiple channel updates in both single instruc-

tion and stream modes.

Figure 76. Option 6 Example: Write to Multi_Input_Ch Register with a Soft-

ware LDAC, Stream Mode (Loop) and Address Ascending

Option 6 is the same as Option 5, except a software LDAC

function is used instead of a hardware LDAC function. The

SW_LDAC_EN_0 register determines which channel is affected

by a software LDAC command.
