Serial channels

Serial channels

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 channels (SSC0 and SSC1). Dedicated baud rate generators set up all

standard baud rates without needing to tune the oscillator. For transmission, reception and

erroneous reception, separate interrupt vectors are provided for ASC0 and SSC0 serial

channels. A more complex mechanism of interrupt source multiplexing is implemented for

ASC1 and SSC1 (XBus mapped).

15.1

Asynchronous/synchronous serial interface (ASC0)

The asynchronous/synchronous serial interfaces (ASC0) provides serial communication

between the ST10F296E and other microcontrollers, microprocessors or external

peripherals.

15.1.1

ASC0 in asynchronous mode

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 2 Mbauds (at 64 MHz of fCPU) is supported in this mode. For

reference, see Figure 64.
