1.2 PIN DESCRIPTIONS
V
DD
and V
SS
. Power is supplied to the MCU via
these two pins. V
DD
is the power connection and
V
SS
is the ground connection.
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
.
The TEST must be held at V
for nor-
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 and Schmitt trigger characteristics.
PA0-PA3.
These 4 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-PB3.
These 4 lines are organized as one I/O
port (B). 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.
PB0-PB3 can also sink 20mA for direct LED
driving.
PB6/ARTIMin, PB7/ARTIMout
. These pins are ei-
ther Port B I/O bits or the Input and Output pins of
the AR TIMER. To be used as timer input function
PB6 has to be programmed as input with or with-
out pull-up. A dedicated bit in the AR TIMER Mode
Control Register sets PB7 as timer output function.
PB6-PB7 can also sink 20mA for direct LED driv-
ing.
PC2-PC4
. These 3 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.
PC2-PC4 can also be used as respectively Data
in, Data out and Clock I/O pins for the on-chip SPI
to carry the synchronous serial I/O signals.
