val = PER_MK_REG(0,4,1,3,8);
or, to make your code more readable and self-documenting, you can use the
symbolic constants for the field values like this:
val = PER_MK_REG(
PER_REG_F0_VAL0,
PER_REG_F1_VAL1,
PER_REG_F2_VAL1,
PER_REG_F3_VAL0,
PER_REG_F4_VAL3
);
You could just as well use variables for the field values. If you used all
constants for the field values, the whole macro resolves down to a single
constant number at compile time.
