bit 3-0: SSPM3:SSPM0: Synchronous Serial Port Mode Select bits
WCOL
R/W-0
WCOL: Write Collision Detect bit
1 = The SSPBUF register is written while it is still transmitting the previous word
(must be cleared in software)
0 = No collision
SSPOV: Receive Overflow Indicator bit
In SPI mode
1 = A new byte is received while the SSPBUF register is still holding the previous data. In case of overflow,
the data in SSPSR is lost. Overflow can only occur in slave mode. The user must read the SSPBUF, even
if only transmitting data, to avoid setting overflow. In master mode the overflow bit is not set since each
new reception (and transmission) is initiated by writing to the SSPBUF register.
0 = No overflow
In I
1 = A byte is received while the SSPBUF register is still holding the previous byte. SSPOV is a "don’t care"
in transmit mode. SSPOV must be cleared in software in either mode.
0 = No overflow
SSPEN: Synchronous Serial Port Enable bit
In SPI mode
1 = Enables serial port and configures SCK, SDO, and SDI as serial port pins
0 = Disables serial port and configures these pins as I/O port pins
In I
1 = Enables the serial port and configures the SDA and SCL pins as serial port pins
0 = Disables serial port and configures these pins as I/O port pins
In both modes, when enabled, these pins must be properly configured as input or output.
CKP: Clock Polarity Select bit
In SPI mode
1 = Idle state for clock is a high level
0 = Idle state for clock is a low level
In I
SCK release control
1 = Enable clock
0 = Holds clock low (clock stretch) (Used to ensure data setup time)
0000 = SPI master mode, clock = F
0001 = SPI master mode, clock = F
0010 = SPI master mode, clock = F
0011 = SPI master mode, clock = TMR2 output/2
0100 = SPI slave mode, clock = SCK pin. SS pin control enabled.
0101 = SPI slave mode, clock = SCK pin. SS pin control disabled. SS can be used as I/O pin
0110 = I
0111 = I
1011 = I
1110 = I
1111 = I
