perhaps I missed something in the early posts, but there is something
strange about all this.

You are bit-banging an SPI interface, why not use the SPI hardware interface
that is in the chip?

The other thing I wonder is how the chip is connected. Are you connecting
the serial data out line from the PIC to the SDI line of the other chip, and
the SDI line of the PIC to the SDO line of the other chip?
