AVR 32 bit microcontroller AT32UC3C0512C Timers/Counters square wave generation

I have been trying for days now to configure the timers of AT32UC3C0512C to
generate a simple square wave. I am sure that the clock is reaching the timer
module, but there is no output. I am posting my code here. Can someone please
help me on this? Its been a long while since I am doing this and continuously
being unsuccessful. I am trying to generate a left aligned pulse with a
considerable duty cycle in this code. Ra compare is set to 0 so the pulse should
be high from the start and should remain high until the counter is lower than Rc
compare. Since Rc compare value is a large one almost equal to the max value
achieved by a 16 bit register, so the duty cycle is supposed to be high. Here is
my code:

void timer_initialize (void)
{
AVR32_TC0.channel[0].ccr = 0x00000001;
AVR32_TC0.channel[0].cmr =0x00018004; //ra compare effect only
AVR32_TC0.channel[0].ra = 0x00000000;
AVR32_TC0.channel[0].rc = 0x00007FFF;
AVR32_TC0.bcr = 0x00000000;
AVR32_TC0.bmr = 0x00000015;
}

int main (void)
{
