_WDWORD(0x40086794, 0x00000033); // Configure PF_5 as FUNC3
_WDWORD(0x40086798, 0x00000033); // Configure PF_6 as FUNC3
_WDWORD(0x4008679C, 0x00000033); // Configure PF_7 as FUNC3
_WDWORD(0x400867A0, 0x00000033); // Configure PF_8 as FUNC3
}
/*-------------------------------------------------------------------
