16-Bit, ±1 LSB Accuracy Voltage Output
Software PD (Power-Down). Equivalent to the PD input.
0: Normal mode.
1: Power-down mode. OUT is internally connected to AGND using a 2kI resistor.
SPI Bus Hold Enable.
0: Bus hold enabled for SPI DOUT output. DOUT stays at its final value after the SPI CS input
rises at the end of the SPI frame.
1: Bus hold disabled for SPI DOUT output. DOUT goes high impedance after the SPI CS input
rises at the end of the SPI frame.
Software Reset. Equivalent to the RST input.
0: Place device in reset.
1: Normal operation.
Set the active low RST_SW bit low to initiate a software reset (equivalent to pulling RST low).
BUSY Input Disable.
0: BUSY input is active.
1: BUSY input is disabled.
Note that this does not affect the BUSY bit in the General Configuration and Status Register.
The BUSY pin is bidirectional. When enabled, it can be pulled down externally to delay DAC
updates.
SPI DOUT Output Disable. DOUT is disabled by default.
0: DOUT output disabled. When DOUT is disabled, the output is pulled low for the duration of
the SPI frame.
1: DOUT output enabled.
Global BUSY status readback.
0: Device is busy transferring DIN code to the DAC register.
1: Device is not busy.
Reserved. Will read back 0.
