<p>The KSDK provides a peripheral driver for the MCG_Lite module of Kinetis devices. </p>
|
|
<h1><a class="anchor" id="MCGLITEFunc"></a>
|
|
Function description</h1>
|
|
<p>The MCG_Lite driver provides three kinds of APIs:</p>
|
|
<ol type="1">
|
|
<li>APIs to get the MCG_Lite frequency.</li>
|
|
<li>APIs for MCG_Lite mode.</li>
|
|
<li>APIs for OSC setup.</li>
|
|
</ol>
|
|
<h2><a class="anchor" id="MCGLITEFreq"></a>
|
|
MCG_Lite clock frequency</h2>
|
|
<p>The <a class="el" href="group__clock.html#gad9df7f4196258f0a9037088784a19380" title="Gets the MCG_Lite output clock (MCGOUTCLK) frequency. ">CLOCK_GetOutClkFreq()</a>, <a class="el" href="group__clock.html#ga352c4e1fcb54bc5656df3299e154a736" title="Gets the MCG internal reference clock (MCGIRCLK) frequency. ">CLOCK_GetInternalRefClkFreq()</a> and <a class="el" href="group__clock.html#gacee790e56c954e537658600aca0b9481" title="Gets the current MCGPCLK frequency. ">CLOCK_GetPeriphClkFreq()</a> functions are used to get the frequency of MCGOUTCLK, MCGIRCLK, and MCGPCLK based on the current hardware setting.</p>
|
|
<h2><a class="anchor" id="MCGLITEMode"></a>
|
|
MCG_Lite mode</h2>
|
|
<p>The function <a class="el" href="group__clock.html#gac486df712cf93a890c084c14956dd750" title="Gets the current MCG_Lite mode. ">CLOCK_GetMode()</a> gets the current MCG_Lite mode.<br/>
|
|
The function <a class="el" href="group__clock.html#ga5e63d4acf979a66bf5b332ca27b9d1cc" title="Sets the MCG_Lite configuration. ">CLOCK_SetMcgliteConfig()</a> sets the MCG_Lite to a desired configuration. The MCG_Lite can't switch between the LIRC2M and LIRC8M. Instead, the function switches to the HIRC mode first and then switches to the target mode.</p>
|
|
<h2><a class="anchor" id="MCGLITEOsc"></a>
|
|
OSC configuration</h2>
|
|
<p>To enable the OSC clock, the MCG_Lite is needed together with the OSC module. The function <a class="el" href="group__clock.html#ga7fd566b301526150b4e2be076006029f" title="Initializes the OSC0. ">CLOCK_InitOsc0()</a> uses the MCG_Lite and the OSC to initialize the OSC. The OSC should be configured based on the board design. </p>
