Hello Nordic! My question probably a simple one but I'm a novice so there's it. I'm looking for a way to get a GPIO port state that was at the moment of GPIOTE event triggering, inside the event handler. Is there any register I can read to get that?
The context: I'm trying to read a two line serial bus of TitanMicro TM1640. The start of transmission is designated by falling DIN line while SCLK line is still high. The time between falling DIN and falling SCLK is about 10 us, so when I'm reading the GPIO from the handler the SCLK is already low.
