I2C_Control_Register Structure
Figure 2-35 shows the functions of each of the 12-bit I2C_Control_Register bits.

I2C_Data_Register Packet Structure
The 72-bit I2C_Data_Register packet is divided into 9 bytes.
• Bytes 9-7 contain the VMON status
• Bytes 6-5 contain ADC result
• Byte 4 controls/reads ADC Mux and ADC Input Attenuator
• Byte 3 controls/reads input pins/ status
• Bytes 2-1 control/read output pins/status
VMON Status Registers
Byte 9, Byte 8 and Byte 7: Byte 9 is the most significant byte and is shifted out last, ending with bit 71, VMON1A.
These bytes consist of the status of VMONxA and VMONxB comparators corresponding to VMON1 through
VMON10 inputs. In the following tables, the number in the parenthesis indicates the bit position within the
I2C_Data_Register Packet. During the I2C_Data_Register write operation, the contents of these bytes are ignored
because the VMON status registers are read only.
