Description


The PEEK command reads a 32-bit value from a specified address and returns it on the stack.

Compatibility


PEEK is specific to newRPL and has no direct equivalent in userRPL.

Usage


PEEK is low-level command which isn't meant for the general public, but mainly to aid the developers on hardware debugging. Careless usage will either cause a crash (data abort exception), or corrupt your precious data.
