Oscillator Control Register
| SYS_XTAL_SEL | Select oscillator clock source for CPUPLL_CLK, SYSPLL_CLK, and SYST_REFCLK 0 (Val_0x0): Select 76.8 MHz ring-oscillator clock 1 (Val_0x1): Select 38.4 MHz crystal-oscillator clock |
| PERIPH_XTAL_SEL | Select oscillator clock source for HFOSC_CLK 0 (Val_0x0): Select 38.4 MHz (76.8 MHz / 2) ring-oscillator clock 1 (Val_0x1): Select 38.4 MHz crystal-oscillator clock |
| CLKMON_ENA | Enable 38.4 MHz crystal-oscillator clock monitor 0 (Val_0x0): Disable clock monitor 1 (Val_0x1): Enable clock monitor |
| XTAL_DEAD | 38.4 MHz crystal-oscillator clock monitor status 0 (Val_0x0): No crystal clock dead found 1 (Val_0x1): Crystal clock dead detected |
