6.4.6 Master/Slave Mode Selection
The selection whether the SSC operates in master mode or in slave mode has to be made
depending on the hardware configuration before the SSC will be enabled.
Normally a specific device will operate either as master or as slave unit. The SSC has no on-chip
support for multimaster configurations (switching between master and slave mode operation).
Operating the SSC as a master in a multimaster environment requires external circuitry for
swapping transmit and receive lines.
