Stellaris^® LM3S5R36 Microcontroller
12.1
■ Efficient transfers using Micro Direct Memory Access Controller (µDMA)
– Dedicated channel for each sample sequencer
– ADC module uses burst requests for DMA
Block Diagram
The Stellaris microcontroller contains two identical Analog-to-Digital Converter modules. These two
modules, ADC0 and ADC1, share the same eight analog input channels. Each ADC module operates
independently and can therefore execute different sample sequences, sample any of the analog
input channels at any time, and generate different interrupts and triggers. Figure 12-1 on page 531
shows how the two modules are connected to analog inputs and the system bus.
