This field defines the size of the HSELx security region address space. Invalid
sizes for the client region must never be programmed. Valid sizes and number of
security regions are product-, client- and client-configuration dependent.
Note: The clients featuring multiple
scalable contiguous security regions have a single SRTOP0 field for all the security
regions.
If this HSELx security region size is set at or below the HSELx low area size, then there is no Security High Area and the MATRIX_SSR settings for the Low Area apply to the whole HSELx security region.
