I2CEN: I2Cx Enable bit
1 = Enables the I2Cx module and configures the SDAx and SCLx pins as serial port pins
0 = Disables I2Cx module. All I
Unimplemented: Read as ‘0’
I2CSIDL: Stop in Idle Mode bit
1 = Discontinues module operation when device enters an Idle mode
0 = Continues module operation in Idle mode
SCLREL: SCLx Release Control bit (when operating as I
1 = Releases SCLx clock
0 = Holds SCLx clock low (clock stretch)
If STREN = 1:
Bit is R/W (i.e., software may write ‘0’ to initiate stretch and write ‘1’ to release clock). Hardware clear at
beginning of slave transmission. Hardware clear at end of slave reception.
If STREN = 0:
Bit is R/S (i.e., software may only write ‘1’ to release clock). Hardware clear at beginning of slave transmission.
IPMIEN: Intelligent Peripheral Management Interface (IPMI) Enable bit
1 = IPMI Support mode is enabled; all addresses Acknowledged
0 = IPMI mode is disabled
A10M: 10-Bit Slave Addressing bit
1 = I2CxADD is a 10-bit slave address
0 = I2CxADD is a 7-bit slave address
DISSLW: Disable Slew Rate Control bit
1 = Slew rate control disabled
0 = Slew rate control enabled
SMEN: SMBus Input Levels bit
1 = Enables I/O pin thresholds compliant with SMBus specification
0 = Disables SMBus input thresholds
GCEN: General Call Enable bit (when operating as I
1 = Enables interrupt when a general call address is received in the I2CxRSR (module is enabled for
0 = General call address disabled
STREN: SCLx Clock Stretch Enable bit (when operating as I
Used in conjunction with SCLREL bit.
1 = Enables software or receive clock stretching
0 = Disables software or receive clock stretching
