Using the Peripheral Management Unit – Part 3: What’s in a Descriptor?
In this third installment, examine each of the eight peripheral management unit (PMU) instructions – also known as descriptors – and learn how they are used in simple programs to transfer data. In “Using the Peripheral Management Unit–Part 4,” we’ll go into the lab to build a program to demonstrate how the PMU can automate some tasks while the CPU sleeps.
