The timing looks similar to SPI, except that it has \Read and \Write
signals that must also be set (with two more i/o pins), in addition to
the normal \CS signal. Therefore, you can use the PIC's hardware
SPI module to provide the interface to the chip.

Read my posts in the following threads, where I talk about how to
determine the SPI mode and use CCS functions to implement it.
