I have this love-hate relationship with TI's documentation. On one hand, once you understand a module, you can use it on any micro. On the other hand, the cross-referenced docs are usually inconsistent and /always/ very confusing. (I still haven't worked out how to connect, let alone use, the sigma-delta ADC, and every time I try to use a timer on an MSP430 I wind up playing with clock control/divider bits for a week. The same signal is called three different things in different documents).
Right now I'm trying to work out how the Timer_A2 module is mapped to I/Os on the F2013, because I want to do some PWM. The chip datasheet has a very confusing table in it, but as near as I can figure out, signal "TA0" is routed to both pins 3 and 7 of the DIP/TSSOP packages, and "TA1" is routed to pins 4, 8 and 13.
I _guess_ you connect whichever pin(s) you want to Timer_A2 using the PxSEL registers.
But WTF are these TA0 and TA1 signals??? The only obvious outputs shown in the timer block diagram are "OUT" and "OUT2 Signal".
According to the MSP430x2xx user guide, there is no such signal TA0/TA1 in the Timer_A module. Searching the user guide for TA0 finds only entries in the USI and ADC modules. Argh.
Any ideas?
