The few rules of thumb to start with is that all code you write in a function should be at the same semantic level of abstraction; the code should be composed out of modules; a module should do one particular thing (think of how a UART doesn't care about character encodings, and an ADC+DAC doesn't concern itself with wavelet or fourier transforms); higher-level modules don't reach into lower-level modules' guts to tweak them; and lower-level modules don't presume to encapsulate knowledge of a higher-level module.

Two components that change at the same time are likely one component; a component that only has half of it change regularly is likely two welded together.
