Usage Notes

20.6.1

Transition to Low Power Consumption Mode

When the POE is used, do not make a transition to software standby mode. In this mode, the POE stops and thus the
high-impedance control of pins cannot operate.
20.6.2

High-Impedance Control When the MTU is Not Selected

If high-impedance control for a pin having a multiplexed MTU pin function is enabled by setting the POECR1 and
POECR2 registers and the high-impedance control condition is satisfied, the output is to be in the high-impedance state
even if the MTU function is not selected for the pin on which it is multiplexed.
20.6.3

When the POE is Not Used

The high-impedance control of some pins can be enabled using the POE after a reset. When the POE is not used, write 0
to the target bits in the POECR1 and POECR2 registers.
