This field defines the size of the HSELx protected region
address space. Invalid sizes for the client region must never be programmed. Valid
sizes and number of protected regions are product, client and client configuration
dependent.
Note: The clients featuring multiple
scalable contiguous protected regions have a single PRTOP0 field for all the
protected regions.
If this HSELx protected region size is set at or below the
MATRIX_PASSR / PASPLITx Protected Areas Split size, then the MATRIX_PSR register
settings apply to the unique protected area then covering the whole HSELx protected
region
