HARDWARE INTERFACE
The pins described in Table 22 comprise the physical interface
between the programming device of the user and the serial port
of the AD9262. The SCLK and CSB pins function as inputs
when using the SPI interface. The SDIO pin is bidirectional,
functioning as an input during write phases and as an output
during readback.

The SPI interface is flexible enough to be controlled by either
PROM or PIC microcontrollers. This provides the user with the
ability to use an alternate method to program the ADC. One
such method is described in detail in the AN-812 Application
Note, MicroController-Based Serial Port Interface (SPI) Boot
Circuit.
