bit 3-0
SSPCON: SYNC SERIAL PORT CONTROL REGISTER (ADDRESS 14h)
WCOL: Write Collision Flag bit
1 = The SSPBUF register was written while still transmitting the previous word (must be
0 = No collision
SSPOV: Synchronous Serial Port Overflow Flag bit
In SPI mode:
1 = A new byte was received while the SSPBUF register is still holding the previous unread
0 = No overflow
In I
1 = A byte was received while the SSPBUF register is still holding the previous unread byte.
0 = No overflow
SSPEN: Synchronous Serial Port Enable bit. When enabled, the SSP pins must be properly
configured as input or output.
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 = Idle state for clock is a high level (Microwire default)
0 = Idle state for clock is a low level (Microwire alternate)
In I
SCK release control
1 = Enable clock
0 = Holds clock low (clock stretch). (Used to ensure data setup time.)
SSPM3:SSPM0: Synchronous Serial Port Mode Select bits
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

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 trans-
mission) is initiated by writing to the SSPBUF register.
SSPOV is a "don’t care" in transmit mode. SSPOV must be cleared in software in either
mode.
