With eight channels, do you mean eight more or less independent timebases
causing interrupts, triggering actions? What are you trying to achieve?

No patience involved as of yet :o)

In Breif, I want to generate eight independent timers. Each timer is
working in continous mode which means it generates periodic
interrupt. That's All,
