Tiva^™ TM4C123GH6PM Microcontroller _{(identical to LM4F230H5QR)}
Register 33: Inter-Integrated Circuit Peripheral Present (PPI2C), offset 0x320
The PPI2C register provides software information regarding the I²C modules.
Important: This register should be used to determine which I²C modules are implemented on this
microcontroller. However, to support legacy software, the DC2 register is available. A
read of the DC2 register correctly identifies if a legacy I²C module is present. Software
must use this register to determine if a module that is not supported by the DC2 register
is present.

Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
