ISTICS
3. OSC1 and OSC2 pins connect a crystal/ceramic resonator, or an external source to the on-chip oscil-
lator; see
more details.
4. On the chip, each I/O port may have up to 8 pads:
– ads that are not bonded to external pins are forced by hardware in input pull-up configuration after reset.

pins to ground.
The configuration of these pads must be kept at reset state to avoid added current consumption.
Pull-up always activated on PE2 see limitation
