1.3 Pin Description
ST52510/513 pins can be set in digital input mode,
digital output mode, interrupt mode or in Alternate
Functions. Pin configuration is achieved by means
of the configuration registers. The functions of the
ST52510/513 pins are described below:

OSCin and OSCout. These pins are internally
connected to the on-chip oscillator circuit. A quartz
crystal or a ceramic resonator can be connected
between these two pins in order to allow correct
use of ST52510/513 with various stability/cost
trade-offs. An external clock signal can be applied
to OSCin: in this case OSCout can be floating.
Without any connection, the device can work with
its internal clock generator (10 MHz)
RESET. This signal is used to reset the ST52510/
513 and re-initialize the registers and control
signals. It is also used when switching from the
Programming Mode to Working Mode and vice
versa.
PA0-PA7, PB0-PB7,PC0-PC5. These lines are
organized as I/O ports. Each pin can be configured
as an input, output (with pull-up, push-pull, weak-
pull-up, open-drain, high-impedance), or as an
interrupt source.

VREF, AIN0-AIN7. These pins are used to input
the analog signals into the A/D Converter. An
analog multiplexer is available to switch these
inputs to the A/D Converter. The pin VREF is used
to input an external A/D Reference Voltage.
T0OUT, T1OUT. These pins output the signals
generated by the PWM/Timer 0 and PWM/Timer 1
peripheral.
TRES, TSTRT, TCLK. These pins are related to
the PWM/Timer 0 peripheral and are used for Input
Capture and event counting. The TRES pin is used
to set/reset the Timer; the TSTRT pin is used to
start/stop the counter. The Timer can be driven by
the internal clock or by an external signal
connected to the TCLK pin.
INT. This pin is used as input for the Non-Maskable
(top level) interrupt. The interrupt signal is detected
only if the pin is configured in Alternate Function.
SCL, SDA. These pin are used respectively as
Serial Clock and Serial Data I/O in I
protocol. They are used also in Programming
Mode to receive and transmit data.
TX, RX. Serial data output of SCI Transmitter block
(TX) and Serial data input of the SCI Receiver
block (RX).
SCK, MISO, MOSI, SS. These pins are used by
the Serial Peripheral Interface (SPI) peripheral.
SCK is the serial clock line. MISO (Master In Slave
Out) and MOSI (Master Out Slave In) are the serial
data lines, which work in input or in output
depending on if the device is working in slave or
master mode. The SS pin allows the selection of
the device master/slave mode.
