Note 1:
If SPIEN = 1, these functions must be assigned to available RPn/RPIn pins before use. See Section 10.4
“Peripheral Pin Select (PPS)” for more information.
SPITBF: SPIx Transmit Buffer Full Status bit
1 = Transmit not yet started, SPIxTXB is full
0 = Transmit started, SPIxTXB is empty
In Standard Buffer mode:
Automatically set in hardware when the CPU writes to the SPIxBUF location, loading SPIxTXB.
Automatically cleared in hardware when the SPIx module transfers data from SPIxTXB to SPIxSR.
In Enhanced Buffer mode:
Automatically set in hardware when the CPU writes to the SPIxBUF location, loading the last available
buffer location.
Automatically cleared in hardware when a buffer location is available for a CPU write.
SPIRBF: SPIx Receive Buffer Full Status bit
1 = Receive complete, SPIxRXB is full
0 = Receive is not complete, SPIxRXB is empty
In Standard Buffer mode:
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.
In Enhanced Buffer mode:
Automatically set in hardware when SPIx transfers data from the SPIxSR to the buffer, filling the last
unread buffer location.
Automatically cleared in hardware when a buffer location is available for a transfer from SPIxSR.
