Serial Clock 0 (SC0)—This signal’s function is determined by
whether the SCLK is in Synchronous or Asynchronous mode.
Port C GPIO 3 (PC3)—This signal is a GPIO signal called PC3
when the SSI SC0 function is not being used.
After reset, the default state is GPIO input.
Serial Clock 1 (SC1)—The SSI uses this bidirectional signal to
control flag or frame synchronization. This signal’s function is
determined by whether the SCLK is in Synchronous or
Asynchronous mode.
SC0 and SC1 are independent serial I/O flags but may be used
together for multiple serial device selection.
Port C GPIO 4 (PC4)—This signal is a GPIO signal called PC4
when the SSI SC1 function is not being used.
After reset, the default state is GPIO input.
Serial Clock 2 (SC2)—The SSI uses this bidirectional signal to
control frame synchronization only. As with SC0 and SC1, its
function is defined by the SSI operating mode.
Port C GPIO 5 (PC5)—This signal is a GPIO signal called PC5
when the SSI SC1 function is not being used.
After reset, the default state is GPIO input.

In Synchronous mode, this signal is used as a serial I/O
flag.
In Asynchronous mode, this signal receives clock I/O.
In Asynchronous mode, this signal is frame sync I/O.
For Synchronous mode with continuous clock, this
signal is a serial I/O flag and operates like the SC0.
