Result
SPI interrupt is set when the SPI Rx buffer is full.
SPI interrupt is set when the SPI Tx buffer is empty.

AUTO_SS
1
Master mode, SS output control (see Figure 110 ).
AUTO_SS

Result
The SS pin is held low while this bit is cleared. This allows manual chip select
control using the SS pin.
Single byte read or write. The SS pin goes low during a single byte
transmission and then returns high.
Continuous Transfer. The SS pin goes low during the duration of the multibyte
continuous transfer and then returns high.

SS_EN
0
Slave mode, SS input enable.
When this bit is set to Logic 1, the SS pin is defined as the slave select input pin for the SPI
slave interface.

Result
If the SPI2CRx SFR has not been read when a new data byte is received,
the new byte is discarded.
If the SPI2CRx SFR has not been read when a new data byte is received,
the new byte overwrites the old data.
