Table 21 on pg 53 is confusing. There are two columns, P2SEL.6/P2SEL.7 and P2SEL2.6/P2SEL2.7. I have no idea what the P2SEL2.6/P2SEL2.7 column is referring to (and it has the opposite value of P2SEL.6/P2SEL.7.
Same table says that for Capative Sensing P2SEL2.6 is a 1. Not sure where that gets set or reset. For TA0.1 to be output on P2.6, we need P2DIR.6 to be a 1, P2SEL.6 to be a 1, and P2SEL2.6 to be 0. Now if that is set up P2.6 will output the output of output module for Timer0 CCR1. You have to have the timer h/w programmed properly and the output mode set properly to see something meaningful on the TA0.1 pin. I'm most concerned about you not getting P2.6 to act as a port. That is where I would start. Get that working first. You have to have P2DIR.6 set to 1, P2SEL.6 set to 0. Then P2.6 should follow what you wright to bit 6 of P2OUT.
