If you look at the datasheet/user guide for many MSP430 devices, you'll see Timer_x blocks illustrated as well as their associated capture/compare registers. For example, Figure 11-1 from the MSP430FR57xx Family Users Guide. In this diagram, we see references to these "EQU0" and "EQUn" signals all over the place, as well as in the timing diagrams for counters.
Well, the guide never explains anywhere what the origin of these signals are, where they come from, or what their nature even is.
Thus I must ask: What exactly is EQU0 ... EQUn ???
As a tangent to this question ... why do some output modes not matter "because EQU0 = EQUn" ? What does this even mean?
