LPC55S69 : power down main oscillator

[EugeneHiihtaja]

Hello !

I practice with Crystal-less clock configuration and haven't fins how -to powerdown main external oscillator.

For 32Khz one : POWER_EnablePD(kPDRUNCFG_PD_XTAL32K); /* Powered down the XTAL 32 kHz RTC oscillator */

But how-to power down main XTAL ?

Regards,

Eugene

Hi, Eugene,

pls refer to the Table 292  in User Manual for LPC55S69.

In other words, you can set the PDEN_XTAL32K in Power configuration register 0 to power down the external 32K oscillator.

Hope it can help you
