Table 3. DAC Selection
The CODEn command (B[23:20] = 0000) 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 DAC latch has
been configured to be transparent. Issuing the CODEn
command with DAC SELECTION = ALL DACs is equiva-
lent to CODE_ALL (B[23:16] = 10000000). See
and
The LOADn command (B[23:20] = 0001) updates the
DAC register content for the selected DAC(s) by upload-
ing the current contents of the CODE register. The
LOADn command can be used with DAC SELECTION =
ALL DACs to issue a software load for all DACs, which
is equivalent to the LOAD_ALL (B[23:16] = 10000001)
command. See
The CODEn_LOAD_ALL command (B[23:20] = 0010)
updates the CODE register contents for the selected
DAC(s) as well as the DAC register content of all DACs.
Channels for which the CODE register content has not
been modified since the last load to DAC register opera-
tion will not be updated to reduce digital crosstalk. Issuing
this command with DAC_ADDRESS = ALL is equivalent to
the CODE_ALL_LOAD_ALL (B[23:16] = 1000001x) com-
mand. The CODEn_LOAD_ALL command by definition
will modify at least one CODE register. To avoid this, use

the LOADn command with DAC SELECTION = ALL DACs
or use the LOAD_ALL command. See
The CODEn_LOADn command (B[23:20] = 0011)
updates the CODE register contents for the selected
DAC(s) as well as the DAC register content of the
selected DAC(s). Channels for which the CODE register
content has not been modified since the last load to DAC
register operation will not be updated to reduce digital
crosstalk. Issuing this command with DAC SELECTION
= ALL DACs is equivalent to the CODE_ALL_LOAD_ALL
command. See
The CODE_ALL command (B[23:16] = 10000000)
updates the CODE register contents for all DACs. See
Table
The LOAD_ALL command (B[23:16] = 10000001) updates
the DAC register content for all DACs by uploading the
current contents of the CODE registers. See
The CODE_ALL_LOAD_ALL command (B[23:16] =
1000001x) updates the CODE register contents for all
DACs as well as the DAC register content of all DACs.
