8.1 GPIO Testing and Results

The GPIO on the F28377D-SEP device provide the basic transport mechanism for all of the other peripherals on the device. Either inputs or outputs, from outputting PWM waveforms, to using communication protocols for input/output, to basic toggling for status updates the GPIO boundary ultimately controls data into and out of the device.

The following test results focus on the integrity of the GPIOs while under Ion beam stimulus, and SEU and SEFI observed.
