Hi,

bits 15:12 of the General Capabilities and Configurations Register is set to the default value 0000b by the master. This means: Maximum 16 Waite States allowed.

But this does not mean that the slave has to use 16 Wait States for every (!) response, even for simple accesses like GET_CONFIGURATION.
