Is there any 8 GPIO pins that is mapped directly to memory so it can be written in one byte on the Teensy 4.1 ? That is if I want to control 8 GPIO at once by writing one byte to memory. There is a special configuration for this type but can't remember what it is called.
Application is for a 8 bit parallel interface to a LCD. This should be faster than SPI ?
