INPUT/OUTPUT FUNCTIONS
General-Purpose I/O
DIO1, DIO2, DIO3, and DIO4 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 = 0x080C
(DIN = 0xB308, and then 0xB20C) to configure DIO1 and
DIO2 as inputs and DIO3 and DIO4 as outputs, with DIO3
set low and DIO4 set high.
In this configuration, read GPIO_CTRL (DIN = 0x3200). The
digital state of DIO1 and DIO2 is in GPIO_CTRL[9:8].

Input Clock Configuration
The input clock function allows for external control sampling in
the ADIS16367. Set GPIO_CTRL[3] = 0 (DIN = 0xB200) and
SMPL_PRD[7:0] = 0x00 (DIN = 0xB600) to enable this
function. See Table 2 and Figure 4 for timing information.
Data Ready I/O Indicator
The factory default sets DIO1 as a positive data-ready indicator
signal. The MSC_CTRL[2:0] bits provide configuration options
for changing the default. For example, set MSC_CTRL[2:0] =
100 (DIN = 0xB404) to change the polarity of the data ready
signal on DIO1 for interrupt inputs that require negative logic
inputs for activation. 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.
