As for mcs51:
SDCC manual (http://sdcc.sourceforge.net/doc/sdccman.pdf) ch. 3.4.1.7


"16 Bit and 32 bit special function register combinations which require a certain access order are better not declared
using __sfr16 or __sfr32. Allthough SDCC usually accesses them Least Significant Byte (LSB) first, this is not
guaranteed."
