SSPCON: SYNCHRONOUS SERIAL PORT CONTROL REGISTER (ADDRESS 14h)
Legend:
R = Readable bit
-n = Value at POR
WCOL: Write Collision Detect bit
1 = An attempt to write the SSPBUF register failed because the SSP module is busy
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
0 = No overflow
In I
1 = A byte is received while the SSPBUF register is still holding the previous byte. SSPOV is
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
CKP: Clock Polarity Select bit
In SPI mode:
1 = Transmit happens on falling edge, receive on rising edge. Idle state for clock is a high level.
0 = Transmit happens on rising edge, receive on falling edge. 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.)
SSPM<3:0>: Synchronous Serial Port Mode Select bits
0000 = SPI Master mode, clock = OSC/4
0001 = SPI Master mode, clock = OSC/16
0010 = SPI Master mode, clock = OSC/64
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.
