– Dedicated channel for each sample sequencer
– ADC module uses burst requests for DMA
Block Diagram
The TM4C1232E6PM microcontroller contains two identical Analog-to-Digital Converter modules.
These two modules, ADC0 and ADC1, share the same 12 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 732 shows how the two modules are connected to analog inputs and the system bus.
