LPC2378_timer1

hi all

this is how i initialize the timer1

void init_timer1(void)
{ T1MR1 = 15999999;//15990;
T1MCR = 3; T1TCR = 1;
T1CTCR = 0x00;
VICVectAddr5 = (unsigned long)T1_IRQHandler; VICVectCntl5 = 14;
VICIntEnable = (1 << 5);
}

__irq void T1_IRQHandler (void)
{ volatile unsigned int pin_status; pin_status = FIO4PIN;

if((pin_status & 0x20000000) == 0x20000000)
{ FIO4CLR |= 0x20000000;
} else
{ FIO4SET |= 0x20000000;
} }

this timer1 is not working in timer0 and timer1 i have initialized as similar
which toggles the pin every one sec.here timer0 generates the interrupt and i get the pin toggled but i have the problem with timer1 the pin doesnt toggle so i doubt tht timer1 is not initialized or its not able to generate interrupt so can any one help me to rectify the doubt i have given the code how i initialize the time and the interrupt code ...the default PCONP is set .
