4.1.16 Power Control Interface
Power Good (PWR_OK)
The microETXexpress®-PV-XT COM provides an external input for a power-good
signal (pin B24). The implementation of this subsystem complies with the COM
Express® Specification. PWR_OK must be high-level (> 1.7V) to power on the
module in normal ATX mode.
Power Button (PWRBTN#)
The power button (pin B12) is available through the module connector as
defined in the pin-out list. To start the module using the power button the
PWRBTN# signal must be at least 50ms (50ms
≤ t < 4sec) at low-level power.
To force a power-off the module, press and hold the power button for at least
four seconds. Depending on the OS in use, only one press of the Power button
initiate the clean power down of the module.
Reset Button (SYS_RESET#)
The reset button (pin B49) is available through the module connector as
defined in the pin-out list. The module stays in reset as long as SYS_RESET#
