*不懂英文，这两脚的解释是：
41 FCCM_NB Diode emulation control signal for Intersil MOSFET Drivers. When FCCM_NB is LOW, diode emulation at
the driver this pin connects to is allowed. A resistor from FCCM_NB pin to GND configures the PWM_Y
and floating internal gate driver [BOOTX, UGATEX, PHASEX, LGATEX pins] to support Phase 3 of the Core
VR and Phase 1 of the Northbridge VR. The FCCM_NB resistor value also is used to set the slew rate for
the Core VR and Northbridge VR.
42 PGOOD_NB Open-drain output to indicate the Northbridge portion of the IC is ready to supply regulated voltage.
Pull-up externally to VDDP or 3.3V through a resistor.

在线翻译：

41 fccm_nb二极管仿真控制信号的Intersil的MOSFET驱动器。当fccm_nb低，二极管仿真

此引脚连接到驱动程序是允许的。电阻从fccm_nb引脚到GND配置pwm_y

和浮动内部栅极驱动器[ bootx，ugatex，phasex，lgatex引脚]支持核心的3阶段

VR和VR 1阶段北桥。该fccm_nb电阻器的电阻值是用来设置转换率

核心和北桥VR VR。

42 pgood_nb开漏输出显示的IC北桥部分准备供应电压调节。

把外部vddp或3.3V通过电阻。

装上CPU 试试

在两处缺件下上U试了，没供电，但不掉电，连硬关机都不行。
