ST10F269-T3
14.2 - High Speed Synchronous Serial Channel
(SSC)
The High-Speed Synchronous Serial Interface
SSC provides flexible high-speed serial
communication between the ST10F269-T3 and
other microcontrollers, microprocessors or
external peripherals.
The SSC supports full-duplex and half-duplex
synchronous communication. The serial clock
signal can be generated by the SSC 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 SSC with a separate serial clock
signal. The serial channel SSC has its own
dedicated 16-bit Baud rate generator with 16-bit
reload capability, allowing Baud rate generation
independent from the timers.
