DMAC-Slide2

Here is a diagram of the RX Direct Memory Access Controller, or DMAC. The DMAC sits on Internal Main bus 2, and can acts as a master on this bus, giving the DMAC access to on-chip RAM and flash as well as on-board peripherals. The DMAC is tightly coupled to the Interrupt Control Unit or ICU, allowing the ICU to trigger DMA transfers and the DMAC to generate interrupts to the CPU core. There are four independent channels in the RX DMAC, and each one has a dedicated set of control registers.
