(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.
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: Stop in Idle Mode bit
1 = Discontinue module operation when device enters Idle mode
0 = Continue module operation in Idle mode
Unimplemented: Read as ‘0’
SPIBEC<2:0>: SPIx Buffer Element Count bits (valid in Enhanced Buffer mode)
Master mode:
Number of SPI transfers pending.
Slave mode:
Number of SPI transfers unread.
SRMPT: Shift Register (SPIxSR) Empty bit (valid in Enhanced Buffer mode)
1 = SPIx Shift register is empty and ready to send or receive
0 = SPIx Shift register is not empty
SPIROV: Receive Overflow Flag bit
1 = A new byte/word is completely received and discarded
(The user software has not read the previous data in the SPIxBUF register.)
0 = No overflow has occurred
SRXMPT: Receive FIFO Empty bit (valid in Enhanced Buffer mode)
1 = Receive FIFO is empty
0 = Receive FIFO is not empty
SISEL<2:0>: SPIx Buffer Interrupt Mode bits (valid in Enhanced Buffer mode)
111 = Interrupt when the SPIx transmit buffer is full (SPITBF bit is set)
110 = Interrupt when the last bit is shifted into SPIxSR; as a result, the TX FIFO is empty
101 = Interrupt when the last bit is shifted out of SPIxSR; now the transmit is complete
100 = Interrupt when one data is shifted into the SPIxSR; as a result, the TX FIFO has one open spot
011 = Interrupt when the SPIx receive buffer is full (SPIRBF bit set)
010 = Interrupt when the SPIx receive buffer is 3/4 or more full
001 = Interrupt when data is available in the receive buffer (SRMPT bit is set)
000 = Interrupt when the last data in the receive buffer is read; as a result, the buffer is empty (SRXMPT
