When program space (PS) is mapped to data space by enabling the PSV (CORCON<2>) bit, and
the X space EA falls within the visible program space window, the read or write cycle is redirected
to the address in program space. Accessing data from program space takes up to 3 instruction
cycles.
Instructions operating in PSV address space are subject to RAW data dependencies and
consequent instruction stalls, just like any other instruction.
Consider the following code segment:
This sequence of instructions would take 5 instruction cycles to execute. 2 instruction cycles are
added to perform the PSV access via W1. Furthermore, an instruction stall cycle is inserted to
resolve the RAW data dependency caused by W2.
