Enabling GPIO pin after a certain delay

I need to enable/disable certain GPIO ports after certain delay intervals. In my application I cannot use any of the timer counters as I'm using all of the 48 PIO ports(42 pins for LQFP48- LPC1114) for GPIO.
Is there a way to solve it. If so,can someone please show me a example code or link to example code.

thanks!!

You can use any of 6 timers available in LPC11xx. The timers do not require external pin connection for operation. Look at LED blinkers examples provided by CodeRed - they use different timers without pin connections.

Hello Muppiri,

Can you be more specific?

What do you mean by enabling of disabling GPIO? Making them high or low?
Cann't you give a specific timer a double function? In the interrupt routine a counter vaiabel is incremented and this variabel is used in other routines to e.g. stop processes.
System tick timer also used?
Any possibilities in using the watchdog?
