* When the POE3 function is selected in the PFC, the pin is pulled up inside the LSI if
Input/Output Pins
nothing is input to it. The POE3 pin is supported only by the SH7125.

I/O
Output The high-current pins for the MTU2 are placed in
Description
high-impedance state when the pins
simultaneously output an active level (low level
when the output level select P (OLSP) bit of the
timer output control register (TOCR) in the MTU2 is
0 or high level when the bit is 1) for one or more
cycles of the peripheral clock (Pφ).
This active level comparison is done when the
MTU2 output function or general output function is
selected in the pin function controller. If another
function is selected, the output level is not
checked.
Pin combinations for output comparison and high-
impedance control can be selected by POE
registers.
