What is THE valid range in the input threshold control register VLTi?

Latest Updated:04/02/2012

Question:

What is the valid range for the input level switching function in the input threshold control register (VLTi)?

Answer:

The input level switching function is valid only when reading the pin input level and the input level is decided depending on the voltage level of the input threshold value selected in the input threshold control register. Verify items of VIH and VIL CMOS input in the electrical characteristics for input “H” voltage and “L” voltage.
Also verify items of VIH and VIL, other than CMOS input in the electrical characteristics for input “H” voltage and “L” voltage when pins are set as peripheral function pins. Furthermore, peripheral function pins include hysteresis characteristics, so verify VT+-VT- in the electrical characteristics.
