C Control Registers
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: I2Cx 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 can write ‘0’ to initiate stretch and write ‘1’ to release clock). Hardware clears at
beginning of every slave data byte transmission. Hardware clears at end of every slave address byte
reception. Hardware clears at every slave data byte reception.
If STREN = 0:
Bit is R/S (i.e., software can only write ‘1’ to release clock). Hardware clears at beginning of every slave
data byte transmission. Hardware clears 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 is disabled
A10M: I2Cx 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 is disabled
0 = Slew rate control is 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 is disabled
