Spi,Quadrature encoder combined?Insight Please

Hi, I have been trying to combine 2 of the available options of my 
encoder into a cpld with vhdl, I wrote my own bit bang function to 
obtain the absolute position via spi, from here once run I would like to 
pass the 12bit angle position into "count", where the quadrature would 
pick up and start adjusting angle position according to A&B pulses and 
an index "count" reset. both of the codes when separate work perfect, 
but I cannot figure out how to join these two codes together, either 
fails from multiple signal assignment or spi section is not compiled 
correctly and "data" is trimed out. I bet its something simple, but im 
only a few months in as a hobby, with minimal background in avr/arduino. 
Current hardware is a Xilinx Xc9572xL cpld and a 64macrocell Coolrunner 
II, would preffer to have it operating on the 9572. Thank you for your 
help.
