hardware spi is an internal 'peripheral' that handles the data transfers automatically...
Software SPI is program code you create to handle the data transfers.
Nowadays most PICs have SPI hardware built into them,and CCS C compiler has several 'functions' to easily access it.

Try 'googling ' SPI how it works...there are hundreds of articles about it!
Even easier... read the appropriate PIC datasheet section
