这是主板电路 南桥的一小部分
即RTC电路
最后一个信号:SRTCRST# is used to reset portions of the Intel Manageability Engine and should not be
connected to a jumper or button on the platform. The only time this signal gets
asserted (driven low in combination with RTCRST#) should be when the coin cell
battery is removed or not installed and the platform is in the G3 state. Pulling this
signal low independently (without RTCRST# also being driven low) may cause the
platform to enter an indeterminate state. Similar to RTCRST#, it is imperative that
SRTCRST# not be pulled low in the S0 to S5 states.
