basically, this comes from TI includes.
sfrb means thet this defenition of SpecialFunctionRegisterByte.
the sfrb is a magic macro, which should translate, for example ME1_ to ME1
defenition like
volatile unsigned char ME1 asm("0x0004");
Obviously, thai can be done as:
#define ME1 (*(insigned char *)0x0004))
But then gcc issues some stupid code for read-modify-write instructions
(sometimes)
