7.1 Wrong pull-up value on PD[18:3] during reset

The PTC ADC includes pull-up resistors (10 kΩ±30%) connected on PD[18:3] which are normally disabled at reset.

Because of an incorrect control of the internal pull-up disable signal, these pull-up resistors are connected temporarily to the pads at reset.

The 10 kΩ pullups are disconnected when the reset phase is completed and the internal resets have been released. The pull-up value is then ~380 kΩ.
