Bits 0:3, 4:7, 8:11, 12:15, 16:19, 20:23, 24:27, 28:31 – SRTOPx HSELx Security Region Top

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 MATRIX_SASSR / SASPLITx Security Areas Split size, then the MATRIX_SSR settings apply to the unique security area then covering the whole HSELx security region
