Bits 0:3, 4:7, 8:11, 12:15, 16:19, 20:23, 24:27, 28:31 – PASPLITx Protected Areas Split for HSELx Protected Region

This field defines the boundary address offset where the HSELx client-protected region splits into two Protected Areas whose access is controlled according to the corresponding MATRIX_PSR.

If this size is set at or above the HSELx Region Size, then the MATRIX_PSR register settings apply to the unique protected area then covering the whole HSELx Protected Region.
