Hi everyone,

  Do anyone know how I can select module port function on MSP430449 at 
port P1, pins P1.1, P1.3, P1.4, P1.5? I want to select TA0 on P1.1! I 
tried with P1SEL and P!DIR, but I always get third function of the pin 
(for P1.1 I get MCLK).

  P1.0/TA0
  P1.1/TA0/MCLK - I want TA0
  P1.2/TA1
  P1.3/TBOutH/SVSOut - I want TBOutH
  P1.4/TBCLK/SMCLK - I want TBCLK
  P1.5/TACLK/ACLK - I want TACLK

You cannot use the output mode of TA0 on P1.1. If you study the pin 
descriptions in the device data sheet you will see (although it isn't 
exactly crystal clear) that the configuration of a pin depends upon 2 
things. PnSEL, PnDIR. In addition, when PnSEL is '1' the function on
the 
pin is also dependant upon t5he direction control pin. If the pin is 
ascribed two different special functions one of them will be active in 
output mode of the pin, and the other active in the input mode of the 
pin. Thgus P1.1 may act as an output for MCLK, oe as an Input for TA0.
