1.2 PIN DESCRIPTIONS
VDD and VSS. Power is supplied to the MCU via
these two pins. VDD is the power connection and
VSS 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/VPP. The TEST must be held at VSS 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 with Schmitt trigger charac-
teristics. The user can select as option the availa-
bility of an on-chip pull-up at this pin.
PA1-PA5. These 5 lines are organised as one I/O
port (A). Each line may be configured under soft-
ware control as inputs with or without internal pull-
up resistors, input with interrupt generation and
pull-up resistor, open-drain or push-pull outputs.
PA3/ARTIMout and PA4/ARTIMin can be used re-
spectively as output and input pins for the embed-
ded 8-bit Auto-Reload Timer.
In addition, PA1-PA5 can sink 20mA for direct LED
or TRIAC drive.
PB4...PB6. These 3 lines are organised as one I/O
port (B). Each line may be configured under soft-
ware control as inputs with or without internal pull-
up resistors, input with interrupt generation and
pull-up resistor, open-drain or push-pull outputs,
analog inputs for the A/D converter.
PD4...PD7. These 4 lines are organised as one I/O
port (portD). Each line may be configured under
software control as input with or without internal
pull-up resistor, input with interrupt generation and
pull-up resistor, analog input open-drain or push-
pull output. In addition, the pins PD5/TXD1 and
PD4/RXD1 can be used as UART output (PD5/
TXD1) or UART input (PD4/RXD1).
TIMER. This is the TIMER 1 I/O pin. In input mode,
it is connected to the prescaler and acts as ex-
ternal timer clock or as control gate for the internal
timer clock. In output mode, the TIMER pin outputs
the data bit when a time-out occurs.The user can
select as option the availability of an on-chip pull-
up at this pin.
