5.5 Bus Architecture – Peripheral Connectivity

Table 5-9 shows a broad view of the peripheral and configuration register accessibility from each bus master. Peripherals can be individually assigned to the CPU1 or CPU2 subsystem (for example, ePWM can be assigned to CPU1 and eQEP assigned to CPU2). Peripherals within peripheral frames 1 or 2 will all be mapped to the respective secondary master as a group (if SPI is assigned to CPUx.DMA, then McBSP is also assigned to CPUx.DMA).

(1) These modules are on a Peripheral Frame with DMA access; however, they cannot trigger a DMA transfer.
(2) Each CPUx and CPUx.CLA1 can only access its own copy of these registers.
(3) At any given time, only one CPU can perform program or erase operations on the Flash.
(4) The GPIO Data Registers are unique for each CPUx and CPUx.CLAx. When the GPIO Pin Mapping Register is configured to assign a GPIO to a particular master, the respective GPIO Data Register will control the GPIO. See the General-Purpose Input/Output (GPIO) chapter of the TMS320F2837xD Dual-Core Delfino Microcontrollers Technical Reference Manual for more details.
