CODEn Command
The CODEn command updates the CODE register contents for the selected DAC(s). Changes to the CODE register
content based on this command will not affect DAC outputs directly unless the latch has been configured to be trans-
parent (see the CONFIG command). In order to update CODE register content of all DACs, use the CODEn command
with DAC selection = 1XX = all DACs. The CODEn command supports the multibyte protocol. See Table 3 and Table 5.
Table 5. CODEn (000) Command Format
Table 6. LOADn (001) Command Format
LOADn Command
The LOADn command (B[23:20] = 0001) updates the DAC register content for the selected DAC(s) by uploading the
current contents of the CODE register. The LOADn command can be used with DAC SELECTION = 1XX = ALL DACs
to issue a software load for all DACs, which does not alter the existing content of any CODE register (unlike CODEn_
LOAD_ALL command). See Table 3 and Table 6. The LOADn command supports the multibyte protocol.
