(2) Exiting High-Impedance State
The MMT output pins that have entered the high-impedance state by the input level detection are
released from this state by restoring them to their initial states by means of a power-on reset, or by
clearing all the POE flags in ICSR2 (POE4F to POE6F: bits 12 to 14).
13.8.5
To set the POE pin as a level-detective pin, a high level signal must be firstly input to the POE
pin.
