PRODUCTION DATA.
Table 5-26 and Table 5-27 list the access permissions for each bus master on the device. A bus master is a module that can initiate a read or a write transaction on the device.
Each slave module on either the CPU Interconnect Subsystem or the Peripheral Interconnect Subsystem is listed in Table 5-27. Allowed indicates that the module listed in the MASTERS column can access that slave module.
