To send a signal from the low-voltage side to the high-voltage side (e.g. from 3.3 V to 5 V), the signal must be
input at TXI. It will pass through the converter and come out as a higher voltage on the TXO (transmit output)
pin.
On the other hand, a signal that strictly travels from high to low-voltage should pass from RXI to RXO.
Sending a signal from the high side to the low side is less restricted. We can use either the bi-directional
channel or the voltage divider, but we may need to leave the bi-directional channel for converting from low-to-
high.
