Table 74. SPI Control Register(SPI_CTL = 00BAh)
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.

SPI is disabled.
SPI is enabled.
When enabled, the SPI operates as a slave.
When enabled, the SPI operates as a master.
Master SCK pin idles in a Low (0) state.
Master SCK pin idles in a High (1) state.
SS must go High after transfer of every byte of data.
SS can remain Low to transfer any number of data bytes.
