High Speed Synchronous Serial Channel (SSC)
The High-Speed Synchronous Serial Interface
SSC provides flexible high-speed serial communi-
cation between the ST10F168 and other microcon-
trollers, microprocessors or external peripherals.
The SSC supports full-duplex and half-duplex syn-
chronous 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 pro-
vides 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 indepen-
dent from the timers.
SSCBR is the dual-function Baud rate Generator /
Reload register. Table 19 lists some possible
Baud rates against the required reload values and
the resulting bit times for a 25MHz CPU clock.

Note: The deviation errors given in the Table 18
are rounded. To avoid deviation errors use
a Baud rate crystal (providing a multiple of
the ASC0/SSC sampling frequency).
