... X X PIC16F916/917 PIC16F946 DS80238C-page 4 When using an external crystal, the pulse width from rising to falling edge is temperature dependent and may decrease with temperature result, the timer may require an additional oscillation to overflow. Work around Switching to the HFINTOSC after reloading, the timer ensures the Timer1 will see a falling edge before switching back to the external clock source ...
