How to use watchdog timers without RTOS?

Can anyone please give a pseudocode as how to use watchdog timer to keep polling for adc_inputs every 100ms. and The basic settings to be done in halcogen to enable this.Please guide me.

Thanks in advance,

Shruthi

    The watchdog timer is not the correct peripheral to use to generate time events such as reading an ADC input every 100ms. The RTI (real time interrupt) compare is a better choice. The watchdog timer is used to reset the part in case the device is stuck in some "infinite" loop and no longer able to respond and service realtime tasks.
