(1)
This mode allows the module to receive a serial bit stream from another device and store it in
memory.
The shift register clock can be supplied from an external device or from an internal clock.
The word select pin is used as an input flow control. Assuming that SWSP = 0 if SSI_WS is high
then the module will receive the bit stream in blocks of 32 bits, one data bit per clock. If SSI_WS
goes low then the module will complete the current 32-bit block and then stop any further
reception, until SSI_WS goes high again.
(2)
This mode cannot be used.
