1.2 PIN DESCRIPTIONS

OSCin and OSCout. These pins are internally
connected to the on-chip oscillator circuit. A quartz
crystal, a ceramic resonator or an external clock
signal can be connected between these two pins.
The OSCin pin is the input pin, the OSCout pin is
the output pin.
RESET. The active-low RESET pin is used to re-
start the microcontroller.
TEST/V
mal operation. If TEST pin is connected to a
+12.5V level during the reset phase, the
EPROM/OTP programming Mode is entered.
NMI. The NMI pin provides the capability for asyn-
chronous interruption, by applying an external non
maskable interrupt to the MCU. The NMI input is
falling edge sensitive. It is provided with an on-chip
pullup resistor (if option has been enabled), and
Schmitt trigger characteristics.
PA4-PA5. These 2 lines are organized as one I/O
port (A). Each line may be configured under soft-
ware control as inputs with or without internal pull-
up resistors, interrupt generating inputs with pull-
up resistors, open-drain or push-pull outputs, ana-
log inputs for the A/D converter.
PB0, PB2-PB3, PB6-PB7. These 5 lines are or-
ganized as one I/O port (B). Each line may be con-
figured under software control as inputs with or
without internal pull-up resistors, interrupt generat-
ing inputs with pull-up resistors, open-drain or
push-pull outputs. PB6/ARTIMin and PB7/ARTI-

Reset state of PB2-PB3 pins can be defined by op-
tion either with pull-up or high impedance.

direct LED driving.
PC2-PC3. These 2 lines are organized as one I/O
port (C). Each line may be configured under soft-
ware control as input with or without internal pull-
up resistor, interrupt generating input with pull-up
resistor, analog input for the A/D converter, open-
drain or push-pull output.
