Note)

>SPQ[2:0] ----- Please specify link number of source packet.

Valid setting values are 0 - 5.

Processes assuming there are no settings from microcomputer during ‘0’ setting. When 6 - 7 are set, it is regarded to be 5 source packet link.

>DBQ[1:0] ---- Please specify split number of source packet.

‘00’ ---No setting from microcomputer. ‘01’ ---2 splits

‘10’ ---4 splits

‘11’ ---8 splits, 4 splits at DSS

> When the setting values of both SPQ [2:0] and DBQ [1:0] are not ‘0’, follow the setting of SPQ [2:0].

When the setting values of both SPQ [2:0] and DBQ [1:0] are ‘0’ (no setting from microcomputer), LSI automatically executes link process in 1 source packet unit.
