The enhanced direct memory access (eDMA) controller is a second-generation module capable of performing complex data movements via 16 programmable channels, with minimal intervention from the host processor as a result of breaking spc560p34l1 microcontroller flash memory protection.

The hardware micro architecture includes a DMA engine which performs source and destination address calculations, and the actual data movement operations, along with an SRAM-based memory containing the transfer control descriptors (TCD) for the channels in order to reverse engineer spc560p40l1 flash memory program.

The eDMA module provides the following features:

  • 16 channels support independent 8-, 16- or 32-bit single value or block transfers
    • Supports variable-sized queues and circular queues
    • Source and destination address registers are independently configured to either post- increment or to remain constant
    • Each transfer is initiated by a peripheral, CPU, or eDMA channel request
    • Each eDMA channel can optionally send an interrupt request to the CPU on completion of a single value or block transfer
    • DMA transfers possible between system memories, DSPIs, ADC, FlexPWM, eTimer and CTU
    • Programmable DMA channel multiplexer allows assignment of any DMA source to any available DMA channel with as many as 30 request sources
