Page 1031, bit 5 IRS.

“5 IRS I2C reset bit. Note that if IRS is reset during a transfer, it can cause the I2C bus to hang (I2Cx_SDA and I2Cx_SCL are in a high-impedance state).

 0 The I2C is in reset/disabled. When this bit is cleared to 0, all status bits (in ICSTR) are set to their default values.

 1 The I2C is enabled.”
