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 has
triggered or V
DD
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.
V
PP
/TEST
: EPROM programming input. This pin
must be held low during normal operating modes.
V
DD
/V
SS
(see Note 2): Main power supply and
Ground voltages.
V
DDA
/V
SSA
(see Note 2): Power Supply and
Ground 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 100nF decoupling capacitors
on Reset pin (respectively connected to
V
and
V
) will significantly improve product electromag-
netic susceptibility performances.
Note 2
: To enhance reliability of operation, it is
recommended to connect
V
and
V
together
on the application board. The same recommenda-
tions apply to
V
SSA
and
V
SS
.
