Comp HW output on rising edge with minimum GPIO slew rate (glitch is not visible, but still present inside MCU)
General wiev
Comp HW output on rising edge with maximum GPIO slew rate
Comp HW output on falling edge with maximum GPIO slew rate
False falling edge detections
Double rising edge detections
Small noise

First transmittion after RDY assert
overall view
Lastr transmittion before RDY deassert
with delay, it is ok
Transmitting "correct" data (or two byte lost)
suspicious manipulating with data during DE deassert
Stop transmission due RDY and then DE deassert
