This reference guide describes the on-chip peripherals of the TMS320C6000 digital signal processors (DSPs). Main topics are the program memory, the data memory, the direct memory access (DMA) controller, the enhanced DMA controller (EDMA), the host-port interface (HPI), the exansion bus, the external memory interface (EMIF), the boot configuration, the multichannel buffered serial ports (McBSPs), the timers, the interrupt selector and external interrupts, and the power-down modes.
