REGISTER 8-2:
SSPCON: SYNC SERIAL PORT CONTROL REGISTER (ADDRESS 14h)
R/W-0
WCOL
SSPOV
SSPEN
CKP
SSPM3
SSPM2
SSPM1
SSPM0
R = Readable bit
W = Writable bit
U = Unimplemented bit, read
as ‘0’
- n =Value at POR reset
bit7
bit0
bit 7:
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
bit 6:
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 operation, the overflow bit is not set since
each new reception (and transmission) is initiated by writing to the SSPBUF register.
0
= No overflow
In I2C mode
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
bit 5:
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 I2C mode
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.
bit 4:
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 I2C mode
SCK release control
1
= Enable clock
0
= Holds clock low (clock stretch)
bit 3-0: SSPM3:SSPM0: Synchronous Serial Port Mode Select bits
0000
= SPI master operation, clock = FOSC/4
0001
= SPI master operation, clock = FOSC/16
0010
= SPI master operation, clock = FOSC/64
0011
= SPI master operation, 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
= I2C slave mode, 7-bit address
0111
= I2C slave mode, 10-bit address
1011
= I2C firmware controlled master operation (slave idle)
1110
= I2C slave mode, 7-bit address with start and stop bit interrupts enabled
1111
= I2C slave mode, 10-bit address with start and stop bit interrupts enabled
