3.4.3.1.2. Stacks and Shadow Register Sets

Depending on system requirements, the system software can create a dedicated stack for each register set, or share a stack among several register sets. If a stack is shared, the system software must copy the stack pointer each time the register set changes. Use the rdprs instruction to copy the stack register between the current register set and another register set.
