ADIS16260/ADIS16265
BASIC OPERATION
The ADIS16260 and ADIS16265 require only power, ground,
and the four SPI signals to produce data and make it available
to an embedded processor. Figure 9 provides a schematic for
connecting the ADIS16260 and ADIS16265 to a SPI-compatible
processor and includes one of the configurable digital I/O lines.
The MSC_CTRL[2:0] bits are used to configure this line as a data
ready indicator (see the Data Ready I/O Indicator section).

The ADIS16260 and ADIS16265 SPI interface supports full-
duplex serial communication (simultaneous transmit and
receive) and uses the bit sequence shown in Figure 11. Processor
platforms typically support SPI communication with general-
purpose serial ports that require some configuration in their
control registers. Table 6 provides a list of the most common
settings that require attention to initialize the serial port of a
processor for communication with the ADIS16260 and
ADIS16265.

along with references to the bit assignment tables that follow the
generic bit assignments in Figure 10.
