Note: Because the SYNCI, SCL0, SDA0, SCL1, and SDA1 always function, the alternative pin
need always be set to the high or low level regardless of active mode or low power
consumption mode.
If the SCK1, and SI1 input pins are set, the pin level needs be set to the high or low level
regardless of the active mode and low power consumption mode. Note that the pin level
must not reach an intermediate level.
