7.6 Memory Protection Unit (MPU)
The TCI6616 supports five MPUs:
•One MPU is used to protect main CORE/3 CFG TeraNet (CFG space of all slave devices on the TeraNet is protected by the MPU).
•Two MPUs are used for packet DMA (one for DATA PORT and another is for CFG PORT).
•One MPU is used for Semaphore.
•One MPU is used for the RAC.
This section contains MPU register map and details of device-specific MPU registers only. For MPU features and details of generic MPU registers, see the Memory Protection Unit (MPU) for KeyStone Devices User Guide in ‘‘Related Documentation from Texas Instruments’’ on page 59.
The following tables show the configuration of each MPU and the memory regions protected by each MPU.

Table 7-23 shows the privilege ID of each CORE and every mastering peripheral. Table 7-23 also shows the privilege level (supervisor vs. user), security level (secure vs. non-secure), and access type (instruction read vs. data/DMA read or write) of each master on the device. In some cases, a particular setting depends on software being executed at the time of the access or the configuration of the master peripheral.
