Appendix A: Bypass Register
Power ON State Bypass Control Status Register: F3
Bit Field Name Value
5:0 Segment 6 to 1
Segment bypass function control on Power ON state.
Bit[x] corresponds to segment[x+1], ex:
Bit0 control to segment1, … Bit5 control to segment6
0 = Segment[x] disable
1 = Segment[x] enable
7:6 Bypass Mode
These two bits defined the bypass in timer mode or force mode.
Note: The timer will recount while read/write F3 register
Limitation: Changing F3 segment bit during timer counting, the
timing mode segment will controlled by last change value.
Bypass Mode Table:
Bit 7 Bit 6 Action
0 0
Timer Disable:
Disable Timer mode function.
0 1
Force Enable:
Engage bypass relays on segments enable in
segment mask.
1 0
Force Disable:
Disable bypass relays immediately on segments
enabled in mask.
1 1
Timer Enable:
Segments enabled in mask are under Timer
control.
Power OFF State Bypass Control Status Register: F7
Bit Field Name Value
5:0
Segment 6
to 1
Segment bypass function control on Power OFF state.
Bit[x] corresponds to segment[x+1], ex:
Bit0 control to segment1, … Bit5 control to segment6
0 = Segment[x] disable
1 = Segment[x] enable
7:6 Unused Unused.
Slot Select Register: F9
Bit Field Name Value
7:0
Slot ID bit 7
to 0
Main board: The bypass function workable while Slot ID set to
0x00h
Lan module: The bypass function workable while Slot ID value
meet H/W setting, The value do not set to 0x00h
Note: If all of boards not fill slot id value on platform, read all
registers will return 0xFF
