MANAGEMENT INTERFACE
The structure of the memory map is shown in Figure 1, which is accessible over a 2-wire serial interface at the 8-bit
address 1010000X (A0h). The normal 256 byte I2C address space is divided into low and upper blocks of 128 Bytes. The
lower block of 128 Bytes is always directly available and is used for the diagnostics and control function. Multiple blocks of
memories are available in the upper 128 Bytes of the address space. These are individually addressed through a table select
Byte which the user enters into a location in the lower address space. Thus, there is a total available address space of 128*256
= 32 Kbytes in this upper memory space. The contents of Table 01h are listed in Table 1 below. Please refer SFF INF-8077i
(Revision 4.5) for detailed information.
