NOTE) When the USI1 block is an I2C mode and the corresponding port is an sub-function for SCL1/SDA1 pin,
The SCL1/SDA1 pins are automatically set to the N-channel open-drain outputs and the input latch is read
in the case of reading the pins. The corresponding pull-up resistor is determined by the control register.
