The Synchronous Serial Control (SSC) Interface provides flexible high-speed serial
communication between the DSCC4 and other microcontrollers or external peripherals.
The SSC supports full-duplex and half-duplex synchronous communication up to
8.25 MBaud (@ 33 MHz bus clock). 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, or Microwire compatible devices. Transmission and reception of
data is double-buffered. A 16-bit baud rate generator provides the SSC with a separate
internally derived serial clock signal.
The high-speed synchronous serial interface can be configured very flexibly, thus it can
be used with other synchronous serial interfaces (e.g., the ASC0 in synchronous mode),
serve for master/slave or multimaster interconnections or operate compatible with the
popular SPI interface. It allows communicating with shift registers (IO expansion),
peripherals (e.g. EEPROMs) or other controllers (networking).
Data is transmitted or received on the pins MTSR (Master Transmit/Slave Receive) and
MRST (Master Receive/Slave Transmit). The clock signal is an ’output’ or ’input’ on pin
MSCLK.
