Hi!
Be specific about ur requirements. Generally speaking
A timer is used to carry out tasks at periodic intervals of time. The period of these intervals can be varied.
As a counter a timer can be used to count the external pulses (either rising or falling) on an external pin that is unique to that timer.
If you need code examples then feel free to ask and i will try to load them for you.
Regards.

timer uses internal clock , counter uses external clock .(in counter, based on external interrupt you can use the interrupt to increment a register , thus you can use the external event as counter .
