What is the default power on value of config register for L6480 stepper motor ic

In the March 2015 datasheet it says that the hex reset value for the config register is 2C88. When I try this on my actual devices (4 of them) I get back 2C08. Based on the value this means that the OC_SD bit is set to 0 - Bridges do not shut down (page 56)

Is the correct value 2C08? Is there an error in the datasheet?

Solved my problem. The SPI mode in my code was wrong, as such the first bit of every byte transaction was being lost.
