Probably the macros for single bits can take confusion. Why do we need a
parameter ?
I am expecting that CSEN(1) sets the bit and CSEN(0) resets the bit, and
this is obviously not the case, because we use them in or-wise or to
mask some bits. For single bits there is no test about the parameter and
I could use CSEN(7), and that is completely wrong.
Is it not better to remove the parameter for single bits ? If we define
for example
SRD (1 << 2)
it is always clear what we want to do and there is no way to generate
confusion. And no need to check the parameter.
Best regards,
Stefano Babic
