What is the Bus?What is the Bus? A data transmission channel between ICs .A data transmission channel between ICs . Two types Bus – Parallel and serial BusTwo types Bus – Parallel and serial Bus How to debug Bus:How to debug Bus:

每一種 每一種 Bus Bus 都有自己的 都有自己的 protocolprotocol ，傳輸資料時無法以，傳輸資料時無法以示波器知道 示波器知道 Bus Bus 現在在做什麼現在在做什麼 (( 一般以 一般以 LA LA 為工具為工具 ).).

系統設計時就確保 系統設計時就確保 Bus Bus 是健全的是健全的 , , 所以………所以……… ....• 先找出那個 先找出那個 Bus Bus 出問題出問題 ..• 若整個 若整個 Bus Bus 不動不動 ,, 先查 先查 CLK, power (CLK, power ( 過 過 bead)bead) 及控制訊號及控制訊號 ..• 目視相關線路零件有無空焊目視相關線路零件有無空焊 ,, 短路或錯料短路或錯料 ..• 以示波器直接掃瞄 以示波器直接掃瞄 Bus Bus 有無短路有無短路 ,, 斷路斷路 ..• 照 照 X ray.X ray.

thermal IC 過熱時會透過 KBC 拉 low 關閉整個系統電源

開啟 +V3A/+V5A 的第一個訊號

+VBAT (lo)= 7.59V = 1.245 X( R1+R2+R3) / (R2+R3)+VBAT (hi)= 8.27V = 1.245 X (R1+R2+R3) / R3

+V5AUXON will declare DC/DC circuits to output +V3A/+V5A

也就是說 DC mode 要等 user 按 power Bottom 才會將 +V5A,+V3A 打開AC mode EC 會自動將 +V5A, +V3A always 的電打開

EC activeEC active這是 EC 的 Power Bottom 訊號

KBC 第一次 收到 PWR_SWIN#_3 low 時 , 會把 RSMRST# 拉 high to reset ICH

Page 52

這是 Power Switch 的訊號

RSMRST# is for KBC to reset ICH

Make sure 32.768KHz is oscillating.

EC_PWRSW# is for KBC to power on ICH, In normal it will be high.

南橋要開電前的必要條件南橋要開電前的必要條件

1. RTC have to be oscillating(32.768KHz).2. RTCRST# have to be high.3. RSMRST# have to be inactive (high).4. PWRBTN# have a trigger.5. LOW_BAT#_3 have to be inactive (high).

If true, then ICH will issue SLP_S3#_3R / SLP_S4#_3R.

電源概分兩種 : PWM & LDO. 但開電的必要條件都一樣 ~~ source power, enable pin

以下兩種線路都是 LDO type

When All +V?S/+V? powers are ready, PWR_GOOD_3 will tie to

MCH_GOOD enable IMVP to generate +VCC_CORE

When +VCC_CORE power is ready, VR_PWRGD_CK410 will go high to inform

system that CPU powers are ready.

When +VCC_CORE is ready, IMVP_CKEN# will go high to enable

PCI_STOP#_3 and CPU_STOP#_3 must be at high otherwise some

clocks will be turned off.

當 CPU power 穩定時 , 用 VR_PWRGD_ck410 經 delay 線路產生 SB_3S_VRMPWR

GD 通知南橋及 KBC – cpu 電源已穩定

為確保 clocks 已穩定送出 , 所以再經一次 delay 送出 PM_PWROK 給南北

橋

南橋南橋 Power GoodPower Good 的來源的來源

南橋收到這兩個 power good 訊號後 , 會 reset 內部的邏輯線路 , 並發 H_PWRGD 告之 CPU 電源控制部分已備妥 . 接著發 PLT_RST# reset 北橋 , 然後起動 DMI 與 北橋溝通 .
