1. The pin DIO7/BOOT is monitored by bootloader after power up or hardware Reset and it should be low to prevent unwanted
bootloader activation
2. The function SPI_IN indicates that the pin is always an input when configured for SPI. Thus in case of SPI master role, it
acts as MISO pin. In case of SPI slave role, this pin act as MOSI. See Table 5.
3. The function SPI_OUT indicates that the pin is always an output when configured for SPI. Thus in case of SPI master role, it
acts as MOSI pin. In case of SPI slave role, this pin act as MISO. See Table 5.
4. DI012 can only be General Purpose Input pins (not output).
