Macro Definition Documentation

#define FSL_SDK_DISABLE_DRIVER_CLOCK_CONTROL 0

When set to 0, peripheral drivers will enable clock in initialize function and disable clock in de-initialize function. When set to 1, peripheral driver will not control the clock, application could control the clock out of the driver.

Note: All drivers share this feature switcher. If it is set to 1, application should handle clock enable and disable for all drivers.

Variable Documentation

volatile uint32_t g_clkinFreq

The CLK_IN pin (clkin) clock frequency in Hz, when the clock is setup, use the function CLOCK_SetClkinFreq to set the value in to clock driver. For example, if CLK_IN is 16MHz,

* CLOCK_SetClkinFreq(16000000);

*

volatile uint32_t g_mclkinFreq

The MCLK in (mclk_in) PIN clock frequency in Hz, when the clock is setup, use the function CLOCK_SetMclkInFreq to set the value in to clock driver. For example, if mclk_In is 16MHz,

* CLOCK_SetMclkInFreq(16000000);
