6 Management Interface XFP Wire Serial Interface Protocol XFP wire serial interface is specified in the Chapter 4 of the XFP MSA specification. The XFP wire serial interface is used for serial ID, digital diagnostics, and certain control functions. The wire serial interface is mandatory for all XFP modules. The wire serial interface address of the XFP module is 00000X(A0h). In order to access to multiple modules on the same wire serial bus, the XFP has a MOD_DESEL(module deselect pin). This pin (which is pull high or deselected in the module) must be held low by the host to select of interest and allow communication over wire serial interface. The module must not respond to or accept wire serial bus instructions unless it is selected. XFP Management Interface XFP Management interface is specified in the Chapter 5 of the XFP MSA specification. The Figure shows the structure of the memory map. The normal 56 Byte address space is divided into lower and upper blocks of 8 Bytes. The lower block of 8 Byte is always directly available and is used for the diagnostics and control functions that must be accessed repeatedly. Multiple blocks of memories are available in the upper 8 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. The upper address space tables are used for less frequently accessed functions and control space for future standards definition.
