The I2CMODE register is called as I2CDIAG (Diagnostic Control) register in the MAS-
The Status register (I2CSTATE) from the Master-only I
The I2CSTATE register is called as I2CDST (Diagnostic State) register in the
The I2CSLVAD register is added for programming the Slave address.
The ACKV bit in the I2CSTATE register enables the Master to verify the
Interrupt Status (I2CISTAT) register and the State (I2CSTATE) register because there
are more interrupt sources. The
DS) bits formerly in the Status register are moved to the State register.
Master only mode version. The I2CDST register provided diagnostic information. The
I2CSTATE register contains status and state information that are useful to software in
operational mode.
TER ONLY mode version. The I2CMODE register provides control for SLAVE modes
of operation as well as the most significant two bits of the 10-bit Slave address.
