PRODUCTION DATA.
The receive FIFO is a 16-bit-wide, 8-location-deep, first-in, first-out memory buffer. Received data from the serial interface is stored in the buffer until read out by the CPU, which accesses the read FIFO by reading the SSIDR register. When configured as a master or slave, serial data received through the SSIRx pin is registered before parallel loading into the attached slave or master receive FIFO, respectively.
