SPI Status Register
The SPI Status Read Only register returns the status of data transmitted using the serial
peripheral interface. Reading the SPI_SR register clears Bits 7, 6, and 4 to a logical 0. See
SPI Status Register (SPI_SR = 00BBh).

SS must go High after transfer of every byte of data.
SS can remain Low to transfer any number of data bytes.
Reserved.
SPI data transfer is not finished.
SPI data transfer is finished. If enabled, an interrupt is
generated. This bit flag is cleared to 0 by a Read of the
SPI_SR register.
An SPI write collision is not detected.
An SPI write collision is detected. This bit flag is cleared to 0
by a Read of the SPI_SR registers.
Reserved.
A mode fault (multimaster conflict) is not detected.
A mode fault (multimaster conflict) is detected. This bit flag is
cleared to 0 by a Read of the SPI_SR register.
