Hi all,

I'm looking for a way to toggle output port directly with the GPIOx_PTOR register as it's specified page 1336:

My problem is to match the teensy3.2 pin with the register. If I want toggle pin 13 (embedded led), what is the register value that I have to set ? GPIOA, B, C, D, E ?

In advance many thanks. Bruno
