It will be nice if we declare the switch case numbers as macros (specific
name)...
I don't see which macros: the values are just 2 booleans.
I am talking about 0x11, 0x10, 0x01 values.. We can give any understandable
names to those...?
#define TRUE_TRUE 0x11
#define TRUE_FALSE 0x10
#define FALSE_TRUE 0x01
or
case ((TRUE << 4) | TRUE:
...
case ((TRUE << 4) | FALSE:
...
case ((FALSE << 4) | TRUE:
...
I would vote for this. Even over the options suggested by Takashi, but
then again this really a matter of taste.
The fact that frame and bit-clock master boolean values are bundled into
a single "enum" field, instead of two dedicated bits, makes all options
bit inconvenient.

Jyri
