Can CNTRi pin be read when a wave pulse is input from this pin and so on?

Latest Updated:12/01/2005

Question:

(Pin)   Can the input level of a CNTRi pin be read when a wave pulse is input from this pin in event counter mode, pulse period measurement mode, or pulse width measurement mode and so on? [2005/12/01]

Answer:

Yes, the input level of the CNTRi pin can be read when a wave pulse is input from the pin. Set the port direction register shared with the CNTRi pin to input mode and read out the port register.
However, make sure the VIH and VIL input levels of both CNTRi and the port are met (VIH: "H" input voltage, VIL: "L" input voltage). (#104766)
