2.4. Operation

When you power-up the Cortex-R5 processor, you must first reset it, as described in Clocking and resets. When it is out of reset, and no longer halted, it starts to fetch and execute instructions from an address and according to the instruction set as described in Reset. The processor initially fetches instructions from, and transfers data to and from either the TCM interfaces or the level-2 memory interfaces.

The processor also responds to stimulus received on its interfaces, for example interrupts, or transactions received on the AXI slave interface.
