If DISSCK = 0, SCKx must be configured to an available RPn pin. See Section 9.4 “Peripheral Pin
Select” for more information.
If DISSDO = 0, SDOx must be configured to an available RPn pin. See Section 9.4 “Peripheral Pin
Select” for more information.
The CKE bit is not used in the Framed SPI modes. The user should program this bit to ‘0’ for the Framed
SPI modes (FRMEN = 1).
If SSEN = 1, SSx must be configured to an available RPn pin. See Section 9.4 “Peripheral Pin Select”
for more information.
Unimplemented: Read as ‘0’
DISSCK: Disable SCKx pin bit (SPI Master modes only)
1 = Internal SPI clock is disabled; pin functions as I/O
0 = Internal SPI clock is enabled
DISSDO: Disable SDOx pin bit
1 = SDOx pin is not used by module; pin functions as I/O
0 = SDOx pin is controlled by the module
MODE16: Word/Byte Communication Select bit
1 = Communication is word-wide (16 bits)
0 = Communication is byte-wide (8 bits)
SMP: SPIx Data Input Sample Phase bit
Master mode:
1 = Input data sampled at end of data output time
0 = Input data sampled at middle of data output time
Slave mode:
SMP must be cleared when SPIx is used in Slave mode.
CKE: SPIx Clock Edge Select bit
1 = Serial output data changes on transition from active clock state to Idle clock state (see bit 6)
0 = Serial output data changes on transition from Idle clock state to active clock state (see bit 6)
SSEN: Slave Select Enable (Slave mode) bit
1 = SSx pin used for Slave mode
0 = SSx pin not used by module; pin controlled by port function
CKP: Clock Polarity Select bit
1 = Idle state for clock is a high level; active state is a low level
0 = Idle state for clock is a low level; active state is a high level
MSTEN: Master Mode Enable bit
1 = Master mode
0 = Slave mode
