High frequency allows high "resolution". You can also use the timer with PPI and GPIOTE to toggle a GPIO at up to 8 MHz if you want.

But why TIMER allow these high frequencies?

Hi,

Although the blinking frequency should only be 8 kHz you are actually trying to process an interrupt 8 million(!) times per second. The CPU is simply not that fast. If you are using a Softdevice it will also have priority over your interrupt, Interrupt priority levels. Try to slow down the interrupt frequency and see if that helps.
