SPI communication failure
In case of "no SCK edge" when CS = '0', the transfer is considered as valid: no error is
returned to the µC. The answer of last command is sent during next transfer.
When the number of SCK period is different from 0 or multiple of 16, next SPI answer is all
zero.

5 V and 3.3 V output compatibility
In order to ensure a full compatibility with 5V and 3.3V MCU peripherals, the pin VDDIO is
dedicated to supply the output buffer of SO. The overall current consumption on Vddio is
"Ivddio". A parasitic current from the pin SO could flow through the pin VDDIO in case of
over-voltage on SO pin vs. VDDIO pin.
