LAN Bypass Function Programming Guide
96E3 uses the Southbridge ICH7 GPIO to control CPLD to realize LAN Bypass/
PassThrough/WDT function.
Programming Sequence
1. program GPO6,34,33, PAIR(3:1) to switch LAN1-2 or LAN3-4 pair
2. program GPO39,38,35 CFG(3:1) to control LAN pair behavior Bypass/
PassThrough/WDT
3. set GPO24, CPLD_SendBIT high about 150ms then set it low about 50ms
to complete the LAN pair conguration progress
