C Slave Address Register
Slave address.
01 = MASTER/SLAVE capable (supports multi-master arbitration) 
with 10-bit slave address.
10 = SLAVE ONLY capable with 7-bit address.
11 = SLAVE ONLY capable with 10-bit address.
IRM—Interactive Receive Mode
Valid in SLAVE mode when software needs to interpret each received byte before
acknowledging. This bit is useful for processing the data bytes following a General Call
Address or if software wants to disable hardware address recognition.
0 = Acknowledge occurs automatically and is determined by the value of the
of the I2CCTL Register.
1 = A receive interrupt is generated for each byte received (address or data). The SCL is
held Low during the Acknowledge cycle until software writes to the I2CCTL Register.
The value written to the
allows software to Acknowledge or Not Acknowledge after interpreting the associated
address/data byte.
GCE—General Call Address Enable
Enables reception of messages beginning with the General Call Address or START byte.
0 = Do not accept a message with the General Call Address or START byte.
1 = Do accept a message with the General Call Address or START byte. When an address
match occurs, the GCA and RD bits in the I
address matched the General Call Address/START byte or not. Following the General Call
Address byte, the software may set the
ing data byte(s) before acknowledging.
SLA[9:8]
Initialize with the appropriate slave address value when using 10-bit slave addressing.
These bits are ignored when using 7-bit slave addressing.
DIAG—Diagnostic Mode 
Selects read back value of the Baud Rate Reload and State registers. 
0 = Reading the Baud Rate registers returns the Baud Rate register values. Reading the
State register returns I
1 = Reading the Baud Rate registers returns the current value of the baud 
rate counter. Reading the State register returns additional state information.
