4 Operation
Figure 4-1 provides a flow chart of the SENtral M&M module’s initialization process, and a
discussion of this process follows in Section 4.1 For the registers, all multi-byte elements are
stored and transmitted using the Little Endian convention: the least significant byte is
stored at the lowest address and transmitted first over the I
2
C bus.
Figure 4-1: SENtral Initialization Sequence
Once the initialization sequence is complete, there are three states in which SENtral may reside:
Normal Operation, Standby, and Pass-Through. Figure 4-2 indicates the recommended way to
get from one state to another, and these states are discussed in detail in Sections 4.2 and 0
(Normal Operation), 4.4 (Standby), and 4.5 (Pass-Through).
