NOTE)
1. When the USIn block is an I2C mode and the corresponding port is an sub-function for SCLn/SDAn
pin, The SCLn/SDAn 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.
