More Information
Summary:A Multi-I/O SPI for precision converters supports a Dual/Quad/Octal SPI to support the speed requirements for digital transmission and also includes a special mode that can be enabled by hardware and/or software to remove the bit scrambling requirement dictated by the JEDEC standard. The special mode removes the scramble requirement and associates each of the bidirectional data lines to a specific channel. The special mode provides backward compatibility that permits the precision converter to be used with controllers that do not natively support the JEDEC standard. Also, the Multi-I/O SPI includes registers divided into a primary region that is accessed only in default mode at power-up for write and/or read operations, and a secondary region that is accessed by any mode enabled in the control register. By restricting access to the "control" register area to a pre-defined mode in the converter at power-up, the access mode can be controlled.
