Serial interface 0 has the low power consumption registers (POFFCR2) that save power when the serial interface
Setting POFFCR2<SIO0EN> to "0" disables the basic clock supply to serial interface 0 to save power. Note that
After reset, POFFCR2<SIO0EN> are initialized to "0", and this renders the serial interface unusable. When using
