Many thanks for all suggestions, new version of code below. Hours have been spent tweaking. New ADC chip tried, wiring triple checked. Unfortunately output is still garbage :(
Below the code is a table of data returned. I put the code in a For x= 1 to 40 loop and ran it multiple times with 1/2VDD, VDD and VSS test voltage inputs. There is a curious pattern to the garbage!
SETPIN 27, DOUT ' pin 27 ADC chip enable active low
PIN(27) = 1 ' ADC chip disabled
SETPIN 11, 20, 19, SPI2 ' assign SPI I/O pins, RX, TX, CLK
pause 20
SPI2 OPEN 100000, 0, 10 ' speed 1MHz, SPI mode 0, 10 bits data
PIN(27) = 0 ' ADC chip enabled
data1 = spi2(104) ' get data from ADC
pin(27)=1 ' ADC chip disabled
SPI2 CLOSE ' close the channel
