Can't generate PWM to timer B assigned pin

Other Parts Discussed in Thread: MSP430FG4618

Hi there,
I'm new about MSP430 and I'm having problems to suceed at an exercise about Timer B.

I'm using Experimenter's Board, IAR and MSP430FG4618.

Experimenter's Board (EB)'s diagram says pin P2.1 is assigned to TB0 and it also has a LED.

My exercise demands that I load up everything needed about timer B to generate a PWM signal through this assigned pin. How does it possible?
I know that I have to set my Timer B as:
16bits.
ACLK = 32768Hz (TBSSEL_1)
Divided by 8 (ID_3).
UP Mode (MC_1)
OUTMODE is Reset/Set (OUTMOD_7)

And set CCR0 and CCR1 to give me a 75% duty cycle. The period doesn't matter yet.

I thought my code would work...

PS.: I haven't reached MSP430 with C yet, that's why it's in Assembly.

#include <msp430xG46x.h>

Making a led blink with interrupts from TimerB, I made it. The problem is doint it by the assigned pin.

If I am misundertanding something, or geting it wrongly, please, let me know the right way!

Thanks so much!
