|
|
<p>The KSDK provides a Peripheral driver for the Low-Leakage Wakeup Unit (LLWU) module of Kinetis devices. The LLWU module allows the user to select external pin sources and internal modules as a wake-up source from low-leakage power modes.</p>
|
|
<h1><a class="anchor" id="LLWUExWkPin"></a>
|
|
External wakeup pins configurations</h1>
|
|
<p>Configures the external wakeup pins' working modes, gets and clears the wake pin flags. External wakeup pins are accessed by <code>pinIndex</code> which is started from 1. Numbers of external pins depend on the SoC configuration.</p>
|
|
<h1><a class="anchor" id="LLWUInWkMdl"></a>
|
|
Internal wakeup modules configurations</h1>
|
|
<p>Enables/disables the internal wakeup modules, and gets the modules flags. Internal modules are accessed by <code>moduleIndex</code> which is started from 1. Numbers of external pins depend the on SoC configuration.</p>
|
|
<h1><a class="anchor" id="LLWUPinFlt"></a>
|
|
Digital pin filter for external wakeup pin configurations</h1>
|
|
<p>Configures the digital pin filter of the external wakeup pins' working modes, gets and clears the pin filter flags. Digital pins filters are accessed by <code>filterIndex</code> which is started from 1. Numbers of external pins depends on the SoC configuration. </p>
