AVR128 translation to PIC C?

Hi

I have the following C code for an AVR128:

Simple answer. No.
There are two seperate values in the original code. 'SPDR', which is presumably the data I/O register, and 'SPSR', which is probably the 'status' register for the transfer. You are trying to use just one value in your 'converted' form. The original, is actually putting the value in 'dataIn', into the SPI transfer register, then waiting for the byte to be transferred, and then reading back the returned byte. SPDR, and SPSR, are hardware registers on the chip.
You can generate basically exactly the same code, if you define the hardware registers and bits (will depend on the PIC, which you don't say), but in fact you don't have to do this. All you need in CCS, to perfrom the same operation, is:

return(spi_read(dataIn));

The spi_read operation, automatically performs the 'wait', to clock the byte out, and won't return till this happens, and will then return the byte clocked back.

Best Wishes
