Can the level of a pin be read on the SH2 if it is in a different function ?

Latest Updated:03/18/2009

Question:

Is it possible to read the level of a pin on the SH2 if it is being used as a different function ?

Answer:

When a port data register is read it will always read the CMOS logic level of that pin so YES you can.Eg. It is possible to detect a break state using an SCI overun interrupt handler.
