Siemens ERTEC 200P-2 Manual page 419

For booting from an external host, the primary boot loader must create a page for the D-
TCM (boot RAM) in the page registers of the HostIF (2x XHIF). The remaining pages can
then be set up specifically by the external host. It makes sense to set up additional pages
for PN-IP, PER-IF, EMC-SDRAM / EMC-SRAM, GDMA and APB peripherals
Address
The following table
shows the paging
register set within
the XHIF module.
