PIC18F2331/2431/4331/4431
REGISTER 19-2: SSPCON: SYNCHRONOUS SERIAL PORT CONTROL REGISTER (CONTINUED)
bit 3-0
SSPM<3:0>: Synchronous Serial Port Mode Select bits⁽³⁾
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
1011 = I²C Firmware Controlled Master mode (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
Note 1:
2:
3:
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 inputs or outputs.
Bit combinations not specifically listed here are either reserved or implemented in I²C™ mode only.
