GPIO2/DAC DISABLE0 and GPIO4/DAC DISABLE1
Subregisters (Address 0x30 and Address 0x31)
The 16-bit, read/write GPIO2/DAC DISABLE0 and GPIO4/DAC
DISABLE1 subregisters specify which DAC channels are disabled
by the GPIO2/DAC DISABLE0 and GPIO4/DAC DISABLE1 pins.
For example, when Bit D0 in the GPIO2/DAC DISABLE0 sub-
register is set to 1, the GPIO2/DAC DISABLE0 pin disables DAC
output VOUT0 when the pin is taken high. On power-up, these
subregisters contain all 0s by default.
For information about how to enable the DAC disable function
on the GPIO2/DAC DISABLE0 and GPIO4/DAC DISABLE1
pins, see the Digital Output Driver Subregister (Address 0x01)
section and the Digital I/O Function Subregister (Address 0x02)
section.

D3 Disable VOUT3 pin R/W This bit specifies whether the VOUT3 output is disabled when the GPIO2/DAC DISABLE0
pin is high.
0 = disable control of VOUT3 by the GPIO2/DAC DISABLE0 pin (default).
1 = enable control of VOUT3 by the GPIO2/DAC DISABLE0 pin.
D2 Disable VOUT2 pin R/W This bit specifies whether the VOUT2 output is disabled when the GPIO2/DAC DISABLE0
pin is high.
0 = disable control of VOUT2 by the GPIO2/DAC DISABLE0 pin (default).
1 = enable control of VOUT2 by the GPIO2/DAC DISABLE0 pin.
D1 Disable VOUT1 pin R/W This bit specifies whether the VOUT1 output is disabled when the GPIO2/DAC DISABLE0
pin is high.
0 = disable control of VOUT1 by the GPIO2/DAC DISABLE0 pin (default).
1 = enable control of VOUT1 by the GPIO2/DAC DISABLE0 pin.
D0 Disable VOUT0 pin R/W This bit specifies whether the VOUT0 output is disabled when the GPIO2/DAC DISABLE0
pin is high.
0 = disable control of VOUT0 by the GPIO2/DAC DISABLE0 pin (default).
1 = enable control of VOUT0 by the GPIO2/DAC DISABLE0 pin.

pin is high.
0 = disable control of VOUT1 by the GPIO4/DAC DISABLE1 pin (default).
1 = enable control of VOUT1 by the GPIO4/DAC DISABLE1 pin.
D0 Disable VOUT0 pin R/W This bit specifies whether the VOUT0 output is disabled when the GPIO4/DAC DISABLE1
pin is high.
0 = disable control of VOUT0 by the GPIO4/DAC DISABLE1 pin (default).
1 = enable control of VOUT0 by the GPIO4/DAC DISABLE1 pin.
