I2CEN: I2Cx Enable bit
1 = Enables the I2Cx module and configures the SDAx and SCLx pins as serial port pins
0 = Disables the 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 is clear
at the beginning of slave transmission. Hardware is clear at the 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 Platform Management Interface (IPMI) Enable bit
1 = IPMI Support mode is enabled; all addresses are 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 specifications
0 = Disables the 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 the SCLREL bit.
1 = Enables software or receive clock stretching
0 = Disables software or receive clock stretching
