Description
Remarks
1
PWR_BTN_N
The pulse generated by the power button on the control
panel is sent to CPU module through power
management FPGA, to power on the system.
2
SUS_S3_N
CPU module output effectively represents that CPU
system has been in the standby status, when 5VSTB
which is controlled by power management FPGA is in the
charging status.
3
SUS_S4_N
CPU module output effectively represents that CPU
system has been in the dormancy status.
4
PWR_OK_N
The output of power supply module is transmitted to the
CPU module by power management FPGA, which
represents the +12V output of power supply module has
been powered on.
