I am working with RX113 and I have 24 Mhz on the peripheral ports.
Which is the fastest frequency that I can have on the input for distinguish from 1 to 0?
This depends on the clock speed you're using and the number of instructions/cycles it takes when reading a digital pin.

Write a software to read the port, check the assembler code and count the execution cycles.Please keep in mind you have to save the read data somewhere.Some items to be considered:How do you want to trigger data read?Which port do you use?Can you switch to another port if needed?Do you already use all available serial interfaces?
