SimpleTech ZeusIOPS manual Selid Function, Selid to Alpa Translation

SEL_ID FUNCTION

The SEL_n (TTL compatible) inputs (defined when -Parallel ESI is de-asserted) provide a binary value of a loop identifier to the drive. These seven (7) signals define 128 possible values and are directly translated into an 8 bit hard Arbitrated Loop Physical Address (AL_PA). Only AL_PAs with neutral disparity are valid values. The drive will attempt to acquire this hard AL_PA during the LIHA phase of the Loop Initialization Process (LIP). Table 7 lists the SEL_ID/AL_PA translation in hexadecimal format.

NOTE: An AL PA value of 0x00 is not valid for an NL_Port. A SEL_ID of 0x7F will force the SSD to obtain a soft address.
