ON-CHIP SPECIAL FUNCTIONREGISTERS (SFR)
The AD5381 contains a number of special function registers
(SFRs), as outlined in Table 14. SFRs are addressed with
REG1 = REG0 = 0 and are decoded using Address Bits
A5 to A0.

SFR COMMANDS
NOP (No Operation)
REG1 = REG0 = 0, A5 to A0 = 000000
Performs no operation but is useful in serial readbackmodeto
clock out data on D
OUT for diagnostic purposes.
BUSY pulses
low during a NOP operation.
Write CLR Code
REG1 = REG0 = 0, A5 to A0 = 000001
DB11 to DB0 = Contain the CLR data
Bringing the CLR line low or exercising the soft clear function
will load the contents of the DACregisters with the data con-
tained in the user configurable CLR register, andwill set
VOUT0 to VOUT39 accordingly. This can be very useful for
setting up a specific output voltage in a clear condition. It is also
beneficial for calibration purposes; the user can load full scale
or zero scale to the clear code register and then issue a hard-
ware or software clear to load this code to all DACs, removing
the need for individual writes to each DAC.Default on power-
up is all zeros.
Soft CLR
REG1 = REG0 = 0, A5 to A0 = 000010
DB11 to DB0 = Don’t Care
Executing this instruction performs the CLR, which is func-
tionally the same as that provided by the external CLR pin. The
DAC outputs areloaded with the data in the CLR code register.
It takes 35 s to fully execute the SOFT CLR, as indicated by the
BUSY low time.
Soft Power-Down
REG1 = REG0 = 0, A5 to A0 = 001000
DB11 to DB0 = Don’t Care
Executing this instruction performs a global power-down
feature that puts all channels into a low powermodethat
reduces the analog supply current to 2 A max and the digi-
tal current to 20 A max. In power-down mode, the output
amplifier can be configured as a high impedance output or
provide a 100 k load to ground. The contentsof all internal
registers are retained in power-down mode. No registercan be
written to while in power-down.
Soft Power-Up
REG1 = REG0 = 0, A5 to A0 = 001001
DB11 to DB0 = Don’t Care
This instruction is used to power up the output amplifiers and
the internal reference. The time to exit power-down is 8 s.
The hardwarepower-downand softwarefunction are internally
combined in a digital OR function.
Soft RESET
REG1 = REG0 = 0, A5 to A0 = 001111
DB11 to DB0 = Don’t Care
This instruction is used to implement a softwarereset. All
internal registers arereset to their default values, which corre-
spond to m at full scale and c at zero scale. The contents of the
DAC registers arecleared, setting all analog outputsto 0 V. The
soft reset activation time is 135 s.
