Memory Privilege Registers

3.6.1

Host Memory Privilege Permission Register (HOSTPRIV)

Memory privilege is an extension of the memory protection defined in the C64x+ megamodule. It defines

the supervisor user mode privilege required to access peripherals that do not inherently have the

protection built in. For more information, see the TMS320C64x+ DSP Megamodule Reference Guide

(literature number SPRU871).

The host memory privilege permission register (HOSTPRIV) configures host memory privilege modes.

HOSTPRIV defines the privilege to be used when an external host uses direct IO with SRIO or HPI to

access any on-chip memory or peripherals or external memory via the EMIF. Writing a 1 makes

supervisor-mode accesses from the peripheral; writing a 0 makes user-mode accesses from the

peripheral. The default for these bits is supervisor-mode access.
