21.3
This section provides a detailed description of all registers accessible in the XEBI.
21.3.1
The registers associated with the XEBI block are shown in
21.3.2
The following sub-sections provide a detailed description of each register and the individual register bits.
All control bits can be written anytime, but this may have no effect on the related function in certain
operating modes. This allows specific configurations to be set up before changing into the target operating
mode.

Depending on the operating mode an available function may be enabled,
disabled or depend on the control register bit. Reading the register bits will
reflect the status of related function only if the current operating mode
allows user control. Please refer the individual bit descriptions.
