Serial channels
15
Serial communication with other microcontrollers, microprocessors, terminals or external peripheral
components is provided by up to four serial interfaces: Two asynchronous/
synchronous serial channels (ASC0 and ASC1) and two high-speed synchronous serial channel (SSC0
and SSC1). Dedicated baudrate generators set up all standard baudrates without the requirement of
oscillator tuning. For transmission, reception and erroneous reception, separate interrupt vectors are
provided for ASC0 and SSC0 serial channel. A more complex mechanism of interrupt sources
multiplexing is implemented for ASC1 and SSC1 (XBUS mapped).
15.1
The asynchronous / synchronous serial interfaces (ASC0 and ASC1) provides serial communication
between the ST10F272M and other microcontrollers, microprocessors or external peripherals.
15.2
In asynchronous mode, 8- or 9-bit data transfer, parity generation and the number of stop bits 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
1.25 Mbaud (at 40 MHz of f
