When enabled, the SDAx and SCLx pins must be configured as inputs.
Bit combinations not specifically listed here are either reserved or implemented in SPI mode only.
When SSPM<3:0> = 1001, any reads or writes to the SSPxADD SFR address actually access the
SSPxMSK register.
This mode is only available when 7-Bit Address Masking mode is selected (MSSPMSK Configuration bit is ‘1’).
WCOL: Write Collision Detect bit
In Master Transmit mode:
1 = A write to the SSPxBUF register was attempted while the I
0 = No collision
In Slave Transmit mode:
1 = The SSPxBUF register is written while it is still transmitting the previous word (must be cleared in
0 = No collision
In Receive mode (Master or Slave modes):
This is a “don’t care” bit.
SSPOV: Receive Overflow Indicator bit
In Receive mode:
1 = A byte is received while the SSPxBUF register is still holding the previous byte (must be cleared in
0 = No overflow
In Transmit mode:
This is a “don’t care” bit in Transmit mode.
SSPEN: Master Synchronous Serial Port Enable bit
1 = Enables the serial port and configures the SDAx and SCLx pins as the serial port pins
0 = Disables the serial port and configures these pins as I/O port pins
CKP: SCKx Release Control bit
In Slave mode:
1 = Releases clock
0 = Holds clock low (clock stretch); used to ensure data setup time
In Master mode:
Unused in this mode.
