3 Wire Spi Interface

SPI has separate pins for input and output data, making it fullduplex Some chips use a halfduplex interface similar to true SPI, but with a single data line Interfaces like this are commonly called "3wire SPI" and can be used with Total Phase SPI products with some simple circuit modifications.

3 wire spi interface. For compatibility, all devices must include bidirectional support in 3wire mode which is the power up default If 4wire mode support is available, the SDO pin may be included and enabled by the user as part of interface configuration but the bidirectional capability of SDIO is still required, even if disabled during configuration. The DS1722 can communicate using either a Motorola Serial Peripheral Interface (SPI) or standard 3wire interface The user can select either communication standard through the SERMODE pin, tying it to VDDD for SPI and to ground for 3wire The device contains both an analog supply voltage and a digital supply voltage (VDDA and VDDD, respectively). Shows the block diagram of 3wire SPI protocol The principle of 3wire SPI protocol is similar with 4wire type Compare with traditional 4wir SPI protocols, the data signal is designed in portshared The advantage of 3wire merged serial data input (SDI) and serial data output (SDO) into one port which is bidirectional.
