FUNCTION
1 00000
8-bit DAC
data
Write DAC data to DAC0 nonvolatile register. Output remains
unchanged.
1 00001
8-bit DAC
data
Write DAC data to DAC1 nonvolatile register. Output remains
unchanged.
1 00010
8-bit DAC
data
Write DAC data to DAC2 nonvolatile register. Output remains
unchanged.
1 00011
8-bit DAC
data
Write DAC data to DAC3 nonvolatile register. Output remains
unchanged.
1 00100
8-bit DAC
data
Write shutdown and mute states to nonvolatile register. A 1 in bits
D7–D4 mutes the respective DAC; a 1 in bits D3–D0 shuts down
the respective DAC (Table 1). Outputs remain unchanged.
1 01000
8-bit DAC
data
Write DAC data to DAC0 volatile register and update OUT0.
All other DAC outputs remain unchanged.
1 01001
8-bit DAC
data
Write DAC data to DAC1 volatile register and update OUT1.
All other DAC outputs remain unchanged.
1 01010
8-bit DAC
data
Write DAC data to DAC2 volatile register and update OUT2.
All other DAC outputs remain unchanged.
1 01011
8-bit DAC
data
Write DAC data to DAC3 volatile register and update OUT3.
All other DAC outputs remain unchanged.
1 01100
8-bit DAC
data
Write shutdown and mute states to volatile register. A 1 in bits
D7–D4 mutes the respective DAC; a 1 in bits D3–D0 shuts down
the respective DAC (Table 1). DAC outputs updated to their
respective mute/shutdown states.
1 1 0 0 0 0 XXXXXXXX
Read DAC0 nonvolatile register. Contents of DAC0 nonvolatile
register available on DOUT. D7–D0 are ignored, and all DAC
outputs remain unchanged.
1 1 0 0 0 1 XXXXXXXX
Read DAC1 nonvolatile register. Contents of DAC1 nonvolatile
register available on DOUT. D7–D0 are ignored, and all DAC
outputs remain unchanged.
1 1 0 0 1 0 XXXXXXXX
Read DAC2 nonvolatile register. Contents of DAC2 nonvolatile
register available on DOUT. D7–D0 are ignored, and all DAC
outputs remain unchanged.
1 1 0 0 1 1 XXXXXXXX
Read DAC3 nonvolatile register. Contents of DAC3 nonvolatile
register available on DOUT. D7–D0 are ignored, and all DAC
outputs remain unchanged.
1 1 0 1 0 0 XXXXXXXX
Read mute/shutdown nonvolatile register. Contents of
mute/shutdown nonvolatile register available on DOUT. D7–D0 are
ignored, and all DAC outputs remain unchanged.
