Integer store instructions
The integer store instructions compute the EA of the memory to be accessed as described
in Chapter 10.1: Data memory addressing modes on page 854.”
The contents of GPR(rS) or GPR(rZ) are stored into the byte, half word, or word in memory
addressed by EA.
The VLE extension supports both big- and little-endian byte ordering for data accesses.
