RETURNn Command
The RETURN command (B[23:20] = 0111) sets the pro-
grammable default RETURN value. This value is used
for all future watchdog, clear, and gate operations when
RET is selected for the DAC using the DEFAULT com-
mand. Issuing this command with DAC_ADDRESS set to
all DACs will program the value for all RETURN registers
and is equivalent to RETURN_ALL. Note: This command is
inaccessible when a watchdog timeout has occurred if the
watchdog timer is configured for safety level = high or max.
CODEn Command
The CODEn command (B[23:20] = 1000) 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
LDAC input is in a low state or the DAC latch has been
configured as transparent using the CONFIG command.
Issuing this command with DAC_ADDRESS set to all
DACs will program the value for all CODE registers and
is equivalent to CODE_ALL.
LOADn Command
The LOADn command (B[23:20] = 1001) updates the
DAC register content for the selected DAC(s) by upload-
ing the current contents of the selected CODE register(s)
into the selected DAC register(s). Channels for which
CODE content has not been modified since the last LOAD
or LDAC operation will not be updated to reduce digital
crosstalk. Issuing this command with DAC_ADDRESS set
to all DACs will update the contents of all DAC registers
and is equivalent to LOAD_ALL.
CODEn_LOADn Command
The CODEn_LOADn command (B[23:20] = 1011)
updates the CODE register contents for the selected
DAC(s) as well as the DAC register content of the select-
ed DAC(s). Channels for which CODE content has not
been modified since the last LOAD or LDAC operation
will not be updated to reduce digital crosstalk. Issuing
this command with DAC_ADDRESS set to all DACs is
equivalent to the CODE_ALL_LOAD_ALL (B[23:16] =
1100_0010) command.
CODEn_LOAD_ALL Command
The CODEn_LOAD_ALL command (B[23:20] = 1010)
updates the CODE register contents for the selected
DAC(s) as well as the DAC register content of all DACs.
Channels for which CODE content has not been modified
since the last LOAD or LDAC operation will not be updat-
ed to reduce digital crosstalk. Issuing this command with
DAC_ADDRESS set to all DACs will update the CODE
and DAC register contents of all DACs and is equivalent
to CODE_ALL_LOAD_ALL. Note this command by defini-
tion will modify at least one CODE register; to avoid this
use the LOAD command with DAC_ADDRESS set to all
DACs or the LOAD_ALL command.
CODE_ALL Command
The CODE_ALL command (B[23:16] = 1100_0000)
updates the CODE register contents for all DACs.
LOAD_ALL Command
The LOAD_ALL command (B[23:16] = 1100_0001)
updates the DAC register content for all DACs by upload-
ing the current contents of the CODE registers to the
DAC registers.
CODE_ALL_LOAD_ALL Command
The CODE_ALL_LOAD_ALL command (B[23:16] =
1100_0010) updates the CODE register contents for all
DACs as well as the DAC register content of all DACs.
RETURN_ALL Command
The RETURN_ALL command (B[23:16] = 1100_0011)
updates the RETURN register contents for all DACs.
NO_OP Commands Command
All unused commands in the space (B[23:16] =
1100_01XX or 1100_1XXX) have no effect on the device,
but will refresh the watchdog timer (if active) with the
safety level set to low.
