It can produce more readable, less error-prone C code though. We use
hardware register definitions such as
typedef struct {
unsigned int x : 8;
unsigned int y : 8;
unsigned int control_bit : 1;
unsigned int dummy1 : 15;
} reg_foo;
at great length for the C definitions for the registers in our chips, and
it really does avoid nasty errors that crop up when using shifting and
masking.
Just another opinion.
