Button Scan Rates: – 0.625 SPS to 80 SPS • Force Level Measurement of Touch Buttons • Independent Channel Operation: – Two Channels for LDC2112 – Four Channels for LDC2114 • Integrated Algorithms to Enable: – Adjustable Force Threshold per Button – Environmental Shift Compensation –...
(e.g. power button pressed, or a wakeup event) or an invalid event (e.g. AC was restored after a power loss). If the event was invalid, the power state prior to the invalid event is restored. Where the prior power state was soft-off, as in the example above, no additional boot...
The power-up sequence executes if one of the following events occurs: • From the OFF state: – The push-button (PB) is pressed (falling edge on PB) or – The AC_DET pin is pulled low (falling edge) or – The PWR_EN is asserted (driven to high-level) or – The main power ...
When the power button is pressed, a power button signal may be asserted to the chipset, in response to which the chipset may instruct the system to turn on (or in other words, to boot up). A state-machine, configured to implement at least a portion of the controller functionality, may...
When the computer is idle or the user has pressed the power button, the OS will put the computer into one of the sleeping (Sx) states. No user-visible computation occurs in a sleeping state. The sleeping sub-states differ in what events can arouse the system to a Working state, and ...
另外,在电源键持续一定时间按下时(步骤S4中为"是"),与周围的亮度无关地直接将电源置于导通状态。 In addition, when the power button is pressed for a certain time (step S4 is "YES"), directly to the power supply in the surrounding brightness regardless of the conductive state.汤山将美...
When nEN is configured for slide-switch mode and the input is deasserted (nEN = HIGH) for an extended period (tMRST), the on/off controller initiates a power-down sequence and goes to standby mode. nEN Dual-Functionality: Push-Button vs. Slide-Switch The nEN digital input can be ...
Although a logic signal from an I/O line, a watchdog timer, or a power-fail output often initiates a manual reset, a pushbutton switch can also be used. When pressed, this type of switch usually bounces, opening and closing several times before settling in the appropriate state. Therefo...
Step 1. Verify the function of the UDC push-button. When the push-button is pressed, register 1000, bit 0 should be on. When the push-button is released, this bit should be off. Step 2. Verify the function of the UDC Test Switch. When the switch is in the up-position, register ...
In this mode, PWRON is used as an input from a push button connected to the PMIC. When the switch is not pressed, the PWRON pin is pulled up to VIN externally through a 100 kΩ resistor. When the switch is pressed, the PWRON pin should be shorted to ground. The PWRON_S bit is...
