7.2 Memory Protection Unit (MPU)
CFG (configuration) space of all slave devices on the TeraNet is protected by the MPU. The 66AK2L06
contains sixteen MPUs:
• MPU0 is used for main TeraNet_3P_B (SCR_3P (B)) CFG.
• MPU1/2/5 are used for QM_SS (one for VBUSM port and one each for the two configuration VBUSP
ports).
• MPU3 is reserved.
• MPU4 is reserved.
• MPU6 is reserved.
• MPU7 is used for OSR data.
• MPU8 is used for EMIF16.
• MPU9 is used for interrupt controllers (GIC, CIC0 and CIC2) connected to TeraNet_3P (SCR_3P).
• MPU10 is used for semaphore.
• MPU11 is used to protect TeraNet_6P_B (SCR_6P (B)) CPU/6 CFG TeraNet.
• MPU12/13/14 are used for SPI0/1/2.
• MPU15 is used DFE, IQNet and NetCP CFG.
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 KeyStone Architecture Memory Protection Unit
(MPU) User's Guide (SPRUGW5).
The following tables show the configuration of each MPU and the memory regions protected by each
MPU.
