Variable Documentation

volatile uint32_t g_xtalFreq

The XTAL (SYSOSC) clock frequency in Hz, when the clock is setup, use the function CLOCK_SetXtalFreq to set the value in to clock driver. For example, if XTAL is 16MHz,

* CLOCK_SetXtalFreq(160000000); // Set the XTALIN value to clock driver.

*

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(160000000); // Set the CLK_IN value to clock driver.

*

volatile uint32_t g_mclkFreq

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(160000000); // Set the MCLK_IN value to clock driver.
