GPIOTE tasks will bypass GPIO operation ?

Question

I want to generate PWM. I set timer2 events_compare[0] to toggle pin 1:

sd_ppi_channel_assign(PWM_LED_HI_CHANNEL, &(NRF_TIMER2->EVENTS_COMPARE[0]) ,&(NRF_GPIOTE->TASKS_OU    T[0]));

I set timer2 cc[3] to generate an interrupt TIMER2_IRQHandler

NRF_TIMER2->INTENSET = TIMER_INTENSET_COMPARE3_Enabled << TIMER_INTENSET_COMPARE3_Pos;

in IRQHandler, I try one of following: NRF_GPIOTE->TASKS_OUT[0] = 1;

and

nrf_gpio_pin_set(SECONDARY_LED_PIN);

Using TASKS_OUT works, but pin_set doesn't

So, If I enable GPIOTE, GPIO operation will be disabled ?

If GPIOTE is enabled and the config register has the pin number, then that pin will be owned completely until that CONFIG or GPIOTE is disabled. 
 Copy paste from the specifications that i found 
 "When an OUT[n] task has been configured to operate on a pin, the pin can only be written from GPIOTE module. Attempting to write a pin as a normal GPIO pin will have no effect."
