15.3
In synchronous mode, data is transmitted or received synchronously to a shift clock which is generated
by the ST10F272M. Half-duplex communication up to 5 Mbaud (at 40 MHz of f
mode.
Table 38.
Note:
15.4
The high-speed synchronous serial interfaces (SSC0 and SSC1) provides flexible high-speed serial
communication between the ST10F272M 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 baudrate generator provides the SSCx with a separate serial clock signal. The serial
channel SSCx has its own dedicated 16-bit baudrate generator with 16-bit reload capability, allowing
baudrate generation independent from the timers.
