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 both 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 both
DACs. 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_ADDRESS = ALL is
equivalent to the CODE_ALL_LOAD_ALL command. 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 both DACs. See
Table
The LOAD_ALL command (B[23:16] = 10000001) updates
the DAC register content for both 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 both
DACs as well as the DAC register content of both DACs.
