SSPM<3:0>: Synchronous Serial Port Mode Select bits
0000 = SPI Master mode, clock = FOSC/4
0001 = SPI Master mode, clock = FOSC/16
0010 = SPI Master mode, clock = FOSC/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
0110 = I²C Slave mode, 7-bit address
0111 = I²C Slave mode, 10-bit address
1000 = I²C Master mode, clock = FOSC / (4 * (SSPADD+1))⁽⁴⁾
1001 = Reserved
1010 = SPI Master mode, clock = FOSC/(4 * (SSPADD+1))⁽⁵⁾
1011 = I²C firmware controlled Master mode (slave idle)
1100 = Reserved
1101 = Reserved
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
In Master mode, the overflow bit is not set since each new reception (and transmission) is initiated by writing to the
SSPBUF register.
When enabled, these pins must be properly configured as input or output.
When enabled, the SDA and SCL pins must be configured as inputs.
SSPADD values of 0, 1 or 2 are not supported for I²C mode.
SSPADD value of ‘0’ is not supported. Use SSPM = 0000 instead.
