+ 1. Connect CONFIG_GPIO_OUTPUT_0 with CONFIG_GPIO_INPUT_0
- 2. Connect GPIO19 with GPIO5
+ 2. Connect CONFIG_GPIO_OUTPUT_1 with CONFIG_GPIO_INPUT_1
- 3. Generate pulses on GPIO18/19, that triggers interrupt on GPIO4/5
+ 3. Generate pulses on CONFIG_GPIO_OUTPUT_0/1, that triggers interrupt on CONFIG_GPIO_INPUT_0/1
