PIN DESCRIPTION (Cont’d)
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 trig-
gered or the VDD is low. It can be used to reset ex-
ternal peripherals.
OSCIN/OSCOUT: Input/Output Oscillator pin.
These pins connect a parallel-resonant crystal, or
an external source, to the on-chip oscillator.
VDD/VSS (see Note 2): Main Power Supply and
Ground voltages.
VDDA/VSSA (see Note 2): Power Supply and
Ground voltages for analog peripherals.
Alternate Functions: Several pins of the I/O ports
assume software programmable alternate func-
tions as shown in the pin description.
Note 1: Adding two 100 nF decoupling capacitors
on the Reset pin (respectively connected to V
DD
and V
SS) will significantly improve product electro-
magnetic susceptibility performance.
Note 2: To enhance the reliability of operation, it is
recommended that VDDA and VDD be connected to-
gether on the application board. This also applies
to VSSA and VSS.
Note 3: The USBOE alternate function is mapped
on Port C2 in QFN40 devices. In SO24 devices it
is mapped on Port B1.
Note 4: The timer OCMP1 alternate function is
mapped on Port A6 in QFN40 pin devices. In
SO24 devices it is not available.
Legend / Abbreviations for Table 2, Table 3:
Type:
I = input, O = output, S = supply
In/Output level: CT = CMOS 0.3 VDD / 0.7 VDD with input trigger
Output level:
10 mA = 10 mA high sink (Fn N-buffer only)
25 mA = 25 mA very high sink (on N-buffer only)
Port and control configuration:
– Input:
float = floating, wpu = weak pull-up, int = interrupt
– Output:
OD = open drain, PP = push-pull, T = True open drain
The RESET configuration of each pin is shown in
bold. This configuration is kept as long as the de-
vice is under reset state.
