bit 3-0 SSPM3:SSPM0: Master Synchronous Serial Port Mode Select bits
SSPxCON1: MSSPx CONTROL REGISTER 1 (SPI™ MODE)
bit 7
WCOL: Write Collision Detect bit (Transmit mode only)
1 = The SSPxBUF register is written while it is still transmitting the previous word
0 = No collision
SSPOV: Receive Overflow Indicator bit
SPI Slave mode:
1 = A new byte is received while the SSPxBUF register is still holding the previous data. In case
0 = No overflow
SSPEN: Master Synchronous Serial Port Enable bit
1 = Enables serial port and configures SCKx, SDOx, SDIx and SSx as serial port pins
0 = Disables serial port and configures these pins as I/O port pins
CKP: Clock Polarity Select bit
1 = Idle state for clock is a high level
0 = Idle state for clock is a low level
0101 = SPI Slave mode, clock = SCKx pin, SSx pin control disabled, SSx can be used as I/O pin
0100 = SPI Slave mode, clock = SCKx pin, SSx pin control enabled
0011 = SPI Master mode, clock = TMR2 output/2
0010 = SPI Master mode, clock = F
0001 = SPI Master mode, clock = F
0000 = SPI Master mode, clock = F

Note:
(must be cleared in software)
of overflow, the data in SSPxSR is lost. Overflow can only occur in Slave mode. The user
must read the SSPxBUF, even if only transmitting data, to avoid setting overflow (must be
cleared in software).
In Master mode, the overflow bit is not set since each new reception (and
transmission) is initiated by writing to the SSPxBUF register.
When enabled, these pins must be properly configured as input or output.
Bit combinations not specifically listed here are either reserved or implemented in
