Hi All,
Could someone please tell me what the purpose of the sfrw macro is?
For example;
#define TA0CTL_ 0x0160
sfrw (TA0CTL,TA0CTL_);
What would be the difference to defining TA0CTL directly to 0x0160 ?
Because #define TA0CTL 0x0160 absolutely useless in C sources.
Expanding TA0CTL = 0; to 0x0160 = 0; is meanless.
sfrw() macro expanded differently when header file included into C or asm source
files.
I can't say why sfrw (TA0CTL, 0x0160) notation not used. Possibly we can change
headers to this notation to preserve global namespace from flooding with
TA0CTL_-like useless names.
