[BugSimpson]

Hello, can someone explain to me how to change the CPU clock? I tried the following
I don't know what to do at the moment... >

const uint8_t cpu_clock_source[][3] = {

//SYSTEM_SOC_CLK_SEL    |   SYSTEM_PLL_FREQ_SEL   |   SYSTEM_PERIOD_SEL

{   0                   ,   0                     ,   0               },
