Fxth87 internal oscilator

[alesgabersek]

Hi all,

Can I drive FXTH87​​​ just on internal 8Mhz oscilator if LF and RF is not in use? ( BLE will be used for comunication instead of LF and RF).

Thnx

A

Hi Ales,

8MHz is provided by the HFO clock and this clock is off in STOP modes.

So it is not possible to use 8MHz HFO in STOP modes. STOP4 mode is used by several firmware functions (refer to the Firmware User Guide). And STOP1 mode is necessary for power saving considerations.

Regards,

Tomas
