The CKE bit is not used in the Framed SPI modes. Program this bit to ‘0’ for the Framed SPI modes
(FRMEN = 1).
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 bit (Slave mode)
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
