bit 7
WCOL:
Write Collision Detect bit
1
= An attempt to write the SSPBUF register failed because the SSP module is busy
(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 over-
flow, 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
2
C 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
SSPEN:
Synchronous Serial Port Enable bit
(1)
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
2
C 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
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
2
C Slave mode:
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.
