Hello wdmagic. I use a different chip but I think the principle will be the same.

Low PORTA.3 : Pause 1 'CHIP SELECT
ShiftOut PORTC.5,PORTC.3,0,[YOUR DATA\16]
'PORTC.5 IS MASTER OUT SLAVE IN (MOSI), PORTC.3 IS SCLK
High PORTA.3 : Pause 1 'deselect - end of word

'use your data\16 for word variable or \8 for byte variable
the 0 after portc.3 sends LSB first or use 1 for MSB first
Hope this helps.
