格式为1.4.12的寄存器值

Question

I need to write a value to a HW register, which has the number format. 1.4.12. I guess the fact they're telling me in the HW specs about the format, that I need to somehow handle the number in a special way. Could someone give me pointers on what to do?

I guess I cannot just write the value passed to me directly in the register?

Answer 1

Too little information to make an exact answer. The format 1.4.12 says nothing without further context.

There should be a specification of the format somewhere in the docs, at least if the documentation is a formal paper and complete.

Sometimes, this "specification" is just a brief explanation how bits are ordered in each register -- but then it has to elaborate on exactly how to map data into each bit.
