Global Commands
The GLOB_CMD register provides trigger bits for several
functions. Setting the assigned bit to 1 starts each operation,
which returns the bit to 0 after completion. For example, set
GLOB_CMD[7] = 1 (DIN = 0xBE80) to execute a software
reset, which stops the sensor operation and runs the device
through its start-up sequence. This sequence includes loading
the control registers with the contents of their respective flash
memory locations prior to producing new data.

Power Management
Setting SMPL_PRD[7:0] ≥ 0x08 also sets the sensor to low
power mode. For systems that require lower power dissipation,
in-system characterization helps users to quantify the associated
performance trade-offs. In addition to sensor performance, low
power mode affects SPI data rates (see Table 2). Use SLP_CNT[7:0]
to put the device into sleep mode for a specified period. For
example, SLP_CNT[7:0] = 0x64 (DIN = 0xBA64) puts the
ADIS16260 and ADIS16265 to sleep for 50 seconds.

INPUT/OUTPUT FUNCTIONS
General-Purpose I/O
DIO1 and DIO2 are configurable, general-purpose I/O lines
that serve multiple purposes according to the following control
register priority: MSC_CTRL, ALM_CTRL, and GPIO_CTRL.
For example, set GPIO_CTRL = 0x0202 (DIN = 0xB302, and
then 0xB202) to configure DIO1 as an input and DIO2 as an
output set high.

Data Ready I/O Indicator
The MSC_CTRL[2:0] bits configure one of the digital I/O lines
as a data ready signal for driving an interrupt. For example, set
MSC_CTRL[2:0] = 100 (DIN = 0xB404) to configure DIO1 as
a negative-pulse data ready signal. The pulse width is between
100 µs and 200 µs over all conditions.

Auxiliary DAC
The 12-bit AUX_DAC line can drive its output to within 5 mV
of the ground reference when it is not sinking current. As the
output approaches 0 V, the linearity begins to degrade (~100 LSB
starting point). As the sink current increases, the nonlinear
range increases. The DAC latch command moves the values of
the AUX_DAC register into the DAC input register, enabling
both bytes to take effect at the same time.
