See Section 10.2.24: I2C PCell identification register 2 (I2C_PCELLID2) on page 99. I 2 C Base +0xFFC I2C_PCellID3 IPCell identification register bits 31:24. See Section 10.2.25: I2C PCell identification register 3 (I2C_PCELLID3) on page 99. 1. All the I 2 C configuration registers (I2C_CR (excluded PE, FTX and FRX bits, etc.) can be modified only when the device is disabled (I2C_CR:PE bit is reset) to avoid synchronization problems with the different clock domains (system, I 2 C clocks).
