Concerto Shared Peripherals are accessible from both the Master Subsystem and the Control Subsystem. The Analog Shared Peripherals include two 12-bit ADCs (Analog-to-Digital Converters), and six Comparator + DAC (10-bit) modules. The ADC Result Registers are accessible by CPUs and DMAs of the Master and Control Subsystems. All other analog registers, such as the ADC Configuration and Comparator Registers, are accessible by the C28x CPU only. The Digital Shared Peripherals include the IPC peripheral and the EPI. IPC is accessible by both CPUs; EPI is accessible by both CPUs and both DMAs.
IPC is used for sending and receiving synchronization events between Master and Control subsystems to coordinate execution of software running on both processors, or exchanging of data between the two processors. EPI is used by this device to communicate with external memory and other devices.
