Yet another inconvenience though is the requirement to be able to trace accesses to the registers. Some of the registers can be accessed in 32 bit mode or 8 bit mode, and this determines how many bytes get
Can you not always use one of the modes only?
I sure can, but what still is not clear to me - how to provide the ability to trace when using structure pointer dereferencing. TPM is a tricky device, and the ability to trace all accesses made debugging much easier.
Is there an example of how tracing should be done when the device is referenced through a memory structure, or do you suggest that the tracing should be dropped?
cheers, /vb
What I am getting at is that the code is much better readable as it is now even though it is in violation of the 'use structure to access registers' requirement.
The purpose is to enable the compiler to perform type checking.
