BOARD_BootClockFRO12M()

void BOARD_BootClockFRO12M

(

void

)

This function executes configuration of clocks.

< Set up the clock sources

< Configure FRO192M

< Ensure FRO is on

< Set up FRO to the 12 MHz, just for sure

< Switch to FRO 12MHz first to ensure we can change the clock setting

< Set FLASH wait states for core

< Set up dividers

< Set AHBCLKDIV divider to value 1

< Set up clock selectors - Attach clocks to the peripheries

< Switch MAIN_CLK to FRO12M
