The nonvolatile store command is ignored if all DACs
are muted or in shutdown.

Register Write Command

This command directly loads the DAC data to the
selected DAC volatile register and updates the respec-

tive output on the rising edge CLK corresponding to
D0. The mute/shutdown volatile register is also accessi-
ble through this command by setting A2 high. A 1 in
any of the four MSBs (D7–D4) mutes the selected DAC;
a 1 in any of the four LSBs (D3–D0) disables the select-
ed DAC (Table 1). The DAC operating states change
