Power & Reset & XTAL: Power & Reset & XTAL:

O2_OP_mode: O2_OP_mode: This PIN is used for RD & factory to update EC firmware or flash programming. Normal should always keep low.

O2_PWM0~5: O2_PWM0~5:

O2_GPO2~3: O2_GPO2~3: Load default -> check status : (1，1) X79 series models use these two pins to control BLK frequency

O2_GPI1 & O2_GPO1: O2_GPI1 & O2_GPO1: Correct: O2_GPI1:H & O2_GPO1:H J_SILENT#(PROCHOT#): If this pin of X79 series model is pulled low at S5, it can’t boot up.

O_PWRBTN#IN_R& O_RSTCON#: Can’t Keep Low O_PWRBTN#IN_R& O_RSTCON#: Can’t Keep Low O2_CUT_PSON#: To keep PWRBTN motion AC Power On -> PWM signal ready -> O2_CUT_PSON#: H When starting to USB BIOS flashback, this pin is also low.

SMBUS & O2_SMB_SWITCH: SMBUS & O2_SMB_SWITCH: Hang”0d0c” : EC check internal register setting of each DIGI+ Power Control.

ASP1000 and ASP1101 are all DIGI power controller, all BIOS setting function can transmit signals through SMBUS to change or adjust IC internal value and in order to get all DIGI VRM function.

Vcc=3.3V Vcc=3.3V Vinsen = 0.86V VRHot = Vcc EN=3.3V

Vcc=3.3V Vcc=3.3V Vinsen = 0.86V VRHot = Vcc EN=3.3V

Vcc=3.3V Vcc=3.3V Vinsen = 0.38V VRHot = 3VSB EN=1V

Step 1: Multi-meter in Ω level : “+” side connects with Source, “-” side connects with Gate. Let MOSFET going into the cut-off state. Step 2: Multi-meter in diode level : “+” side connects with Source, “-” side connects with drain, measure Vf: 0.3V ~ 0.6V Step 3: Multi-meter in resistance level : Step 1: Multi-meter in Ω level : “+” side connects with Source, “-” side connects with Gate. Let MOSFET going into the cut-off state. Step 2: Multi-meter in diode level : “+” side connects with Source, “-” side connects with drain, measure Vf: 0.3V ~ 0.6V Step 3: Multi-meter in resistance level : “+” side connects with drain, “-” side connects with source Value: xM Ω, ~ ∞ Ω, “+” side connects with drain, “-” side connects with gate Value: xM Ω, ~ ∞ Ω “+” side connects with source, “-” side connects with gate Value: xM Ω, ~ ∞ Ω Step 4: Multi-meter in resistance level : “+” side connects with gate, “-” side connects with source ,to turn on MOSFET “+” side connects with drain, “-” side connects with source Value: 0Ω ~~ 10 Ω
