11 / 110 page TMS320F28377D, TMS320F28376D www.ti.com SPRS880 – DECEMBER 2013 2.4 Bus Architecture – Peripheral Connectivity Table 2-6 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). Table 2-6. Bus Master Peripheral Access PERIPHERALS CPU1.DMA CPU1.CLA1 CPU1 CPU2 CPU2.CLA1 CPU2.DMA (BY BUS ACCESS TYPE) Peripherals that can be assigned to CPU1 or CPU2 and have common selectable Secondary Masters Peripheral Frame 1: • ePWM/HRPWM • Sigma-Delta Filter Module (SDFM) Demodulator Y Y Y Y Y Y • eCAP(1) • eQEP(1) • CMPSS(1) • DAC(1) Peripheral Frame 2: • SPI Y Y Y Y Y Y • McBSP • uPP Configuration(1) Peripherals that can be assigned to CPU1 or CPU2 subsystems SCI Y Y I2C Y Y CAN Y Y ADC Configuration Y Y Y Y EMIF1 Y Y Y Y Peripherals and Device Configuration Registers only on CPU1 subsystem EMIF2 Y Y USB and USB RAM Y Y Device Capability, Peripheral Reset, Peripheral Y CPU Select GPIO Pin Mapping and Configuration Y Analog System Control Y uPP Message RAMs Y Y Reset Configuration Y Accessible by only one CPU at a time with Semaphore Clock and PLL Configuration Y Y Peripherals and Registers with Unique Copies of Registers for each CPU and CLA Master(2) System Configuration Y Y (WD, NMIWD, LPM, Peripheral Clock Gating) Flash Configuration(3) Y Y CPU Timers Y Y DMA and CLA Trigger Source Select Y Y GPIO Data(4) Y Y Y Y ADC Results Y Y Y Y Y Y (1) These modules are on a Peripheral Frame with DMA access; however, they do not support DMA transfers. (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 Technical Reference Manual (literature number SPRUHM8) for more details.
