The I2CSTATE Register was called the Diagnostic State (I2CDST) Register in the
MASTER-mode-only version. The I2CDST Register provided diagnostic information.
The I2CSTATE Register contains status and state information that may be useful to
software in an operational mode.
The I2CMODE Register was called the Diagnostic Control (I2CDIAG) Register in the
MASTER-mode-only version. The I2CMODE Register provides control for the
SLAVE modes of operation, as well as the most significant two bits of the 10-bit slave
address.
