11. (F5529 User’s only) Write the code to setup MCLK. It should be
running at 8MHz using the DCO as its oscillator source.
#define MCLK_DESIRED_FREQUENCY_IN_KHZ _________________________
#define MCLK_FLLREF_RATIO __________________________ /(UCS_REFOCLK_FREQUENCY/1024 )
// Set the FLL's clock reference clock to REFO
_________________________( UCS_BASE,
UCS_FLLREF, // Clock you're configuring
_____________________, // Clock Source
UCS_CLOCK_DIVIDER_1 );
//
Config the FLL's freq, let it settle, and set MCLK & SMCLK to use DCO+FLL as clk source
_________________________( UCS_BASE,
MCLK_DESIRED_FREQUENCY_IN_KHZ,
