3.3.11.3 EWM_OUT pin state in low power modes
During Wait, Stop and Power Down modes the EWM_OUT pin enters a high-impedance
state. A user has the option to control the logic state of the pin using an external pull
device or by configuring the internal pull device. When the CPU enters a Run mode from
Wait or Stop recovery, the pin resumes its previous state before entering Wait or Stop
mode. When the CPU enters Run mode from Power Down, the pin returns to its reset
state.
