I'm trying to read a postion on a digital caliper  ( 0" to 24" )

I have a 4 pin header on the caliper 

pin1 = VSS
pin2 = clock      clock speed is 77kHz~ This is measured with a Parallax Oscope
pin3 = DATA
pin4 = VDD

The word starts out with a 55uS pause then the 24 bit word and a 55uS stop

I think My real ? is about the 16 bit REG. and a 24bit value.

How do I get the first 16 bits and then catch the last 8 bits in a REG. without them going by the way side.? And how to read this in to differnt REG.?

I'M confused

The Assembly I have converts this 24bit word to Quadrature and involes a lot of hardware.

Anyhelp or links would be great. 

I also look forward to Your artc.s in Nut&Volts
