Note:
The deviation errors given in the Table 54 and Table 55 are rounded. To avoid deviation
errors use a Baud rate crystal (providing a multiple of the ASC0 sampling frequency)

High speed synchronous serial interfaces
The High-Speed Synchronous Serial Interfaces (SSC0 and SSC1) provides flexible high-
speed serial communication between the ST10F276 and other microcontrollers,
microprocessors or external peripherals.
The SSCx supports full-duplex and half-duplex synchronous communication. The serial
clock signal can be generated by the SSCx itself (master mode) or be received from an
external master (slave mode). Data width, shift direction, clock polarity and phase are
programmable.
This allows communication with SPI-compatible devices. Transmission and reception of data
is double-buffered. A 16-bit Baud rate generator provides the SSCx with a separate serial
clock signal. The serial channel SSCx has its own dedicated 16-bit Baud rate generator with
16-bit reload capability, allowing Baud rate generation independent from the timers.
