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 = Discontinue module operation when device enters an Idle mode
0 = Continue module operation in Idle mode
SCLREL: SCLx Release Control bit (when operating as I
1 = Release SCLx clock
0 = Hold SCLx clock low (clock stretch)
If STREN = 1:
Bit is R/W (i.e., software can write ‘0’ to initiate stretch and write ‘1’ to release clock). Hardware clear
at beginning of every slave data byte transmission. Hardware clear at end every of slave address byte
reception. Hardware clear at every slave data byte reception.
If STREN = 0:
Bit is R/S (i.e., software can only write ‘1’ to release clock). Hardware clear at beginning of every slave
data byte transmission. Hardware clear at end of every slave address byte reception.
IPMIEN: Intelligent Peripheral Management Interface (IPMI) Enable bit
1 = IPMI mode is enabled; all addresses Acknowledged
0 = IPMI mode disabled
A10M: 10-bit Slave Address 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 = Enable I/O pin thresholds compliant with SMBus specification
0 = Disable SMBus input thresholds
GCEN: General Call Enable bit (when operating as I
1 = Enable interrupt when a general call address is received in the I2CxRSR
0 = General call address disabled
STREN: SCLx Clock Stretch Enable bit (when operating as I
Used in conjunction with SCLREL bit.
1 = Enable software or receive clock stretching
0 = Disable software or receive clock stretching
