SPI Control Registers
SPIEN: SPIx Enable bit
1 = Enables module and configures SCKx, SDOx, SDIx and SSx as serial port pins
0 = Disables module
Unimplemented: Read as ‘0’
SPISIDL: SPIx Stop in Idle Mode bit
1 = Discontinues module operation when device enters Idle mode
0 = Continues module operation in Idle mode
Unimplemented: Read as ‘0’
SPIROV: SPIx Receive Overflow Flag bit
1 = A new byte/word is completely received and discarded; the user software has not read the
0 = No overflow has occurred.
Unimplemented: Read as ‘0’
SPITBF: SPIx Transmit Buffer Full Status bit
1 = Transmit has not yet started, SPIxTXB is full
0 = Transmit has started, SPIxTXB is empty
Automatically set in hardware when the CPU writes the SPIxBUF location, loading SPIxTXB. Automatically
cleared in hardware when the SPIx module transfers data from SPIxTXB to SPIxSR.
SPIRBF: SPIx Receive Buffer Full Status bit
1 = Receive complete, SPIxRXB is full
0 = Receive is not complete, SPIxRXB is empty
Automatically set in hardware when SPIx transfers data from SPIxSR to SPIxRXB. Automatically cleared
in hardware when the core reads the SPIxBUF location, reading SPIxRXB.
