The High-Speed Synchronous Serial Interface (SSC) supports full-duplex and
half-duplex synchronous communication. The serial clock signal can be generated by
the SSC internally (master mode), using its own 16-bit baud-rate generator, or can 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
or devices using other synchronous serial interfaces.

Data is transmitted or received on lines TXD and RXD, which are normally connected to
the pins MTSR (Master Transmit/Slave Receive) and MRST (Master Receive/Slave
Transmit). The clock signal is output via line MS_CLK (Master Serial Shift Clock) or input
via line SS_CLK (Slave Serial Shift Clock). Both lines are normally connected to the pin
SCLK. Transmission and reception of data are double-buffered.
