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
(SSC). Two dedicated Baud rate generators set up
all standard Baud rates without the requirement of
oscillator tuning. For 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:
– P3, DP3, ODP3 for pin configuration

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 of f
in this mode.
