AD5270 Unable to program wiper position to memory or fuse.

I am able to communicate with the AD5270, demonstrated through setting and reading of the RDAC. However I am unable to store the desired values in the 50TP memory. I have followed the example set in Table 12, however it never fuses (control register  Bit C3 = 0 always), and when I reset the chip it always goes back to the mid wiper value 511.

Has anyone else encountered this issue? I feel it must be something to do with timings, but I have tried different length of delays to no avail.
