ST10F269
14 - SERIAL CHANNELS
Serial communication with other microcontrollers,
microprocessors, terminals or external peripheral
components is provided by two serial interfaces:
the asynchronous / synchronous serial channel
(ASCO) and the high-speed synchronous serial
channel
generators set up all standard Baud rates without
the
transmission, reception and erroneous reception,
3 separate interrupt vectors are provided for each
serial channel.
14.1 - Asynchronous / Synchronous Serial
Interface (ASCO)
The asynchronous / synchronous serial interface
(ASCO) provides serial communication between
the
microprocessors or external peripherals.
A set of registers is used to configure and to
control the ASCO serial interface:

14.1.1 - ASCO in Asynchronous Mode
In asynchronous mode, 8 or 9-bit data transfer,
parity generation and the number of stop bit can
be selected. Parity framing and overrun error
detection is provided to increase the reliability of
data transfers. Transmission and reception of data
is double-buffered. Full-duplex communication up
to 1.25M Bauds (at 40MHz f
devices) and up to 1MBaud (at 32MHz f
TQFP144 devices) is supported in this mode.
