RESET (see Note 1): Bidirectional. This active low signal forces the initialization of the MCU.
This event is the top priority non maskable interrupt. This pin is switched low when the
Watchdog is triggered or the V
OSCIN/OSCOUT: Input/Output Oscillator pin. These pins connect a parallel-resonant
crystal, or an external source, to the on-chip oscillator.

Alternate functions: Several pins of the I/O ports assume software programmable
alternate functions as shown in the pin description.
Note 1: Adding two 100 nF decoupling capacitors on the Reset pin (respectively connected
to VDD and VSS) will significantly improve product electromagnetic susceptibility
performance.
To enhance the reliability of operation, it is recommended that V

The USBOE alternate function is mapped on Port C2 in QFN40 devices. In SO24 devices it
is mapped on Port B1.
The timer OCMP1 alternate function is mapped on Port A6 in QFN40 pin devices. In SO24
devices it is not available.
