At power-up, the PA1/NRST pin is a reset input pin with pull-up. To be used as a general purpose pin (PA1), it can be

configured only as output open-drain or push-pull, not as a general purpose input. Refer to Section Configuring NRST/PA1

pin as general purpose output in the STM8L15x and STM8L16x reference manual (RM0031).

In the 3.6 V tolerant I/Os, protection diode to VDD is not implemented.
