Description
Port output enable input pins POE0 to POE3
0 to 3
Input
Input request signals to place high-
current pins for MTU2 in high-
impedance state*
Port output enable input pins POE4 to POE7
4 to 7
Input
Input request signals to place high-
current pins for MTU2S in high-
impedance state*
Port output enable input pin 8 POE8
Input
Inputs a request signal to place pins
for channel 0 in MTU2 in high-
impedance state*
Note: * When the selected functions of pins PB16/POE3, PB17/POE7, and PB18/POE8 are for
the POE in the PFC, the pins are pulled up inside the LSI if nothing is input to them.
