ADC32RF45: LMFC MASK RESET

K.Yaita

Part Number: ADC32RF45

Hi Team,

Could you tell me the function of LMFC MASK RESET bit?
What is occured if we set LMFC MASK RESET=1?

The background of the question is my customer wants using SYSREF to reset NCO but not to reset LMFC Counter.
Is it possible?

Best Regards,

Hi Yaita,

I have asked the design team if it's possible to mask SYSREF to LMFC counter and functionality of the LMFC_MASK_RESET bit. I expect a response from them next week. I'll get back to you as soon as I hear from the team.

Regards,

Vijay

Hi Yaita,

Unfortunately, there's no separate SYSREF mask for NCO and LMFC counter. MASK NCO SYSREF bit (description below) when made high, masks sysref for both NCO and LMFC counter.

Hi Vijay-san,

Thank you for your answer. I understand.
Could you also tell me the function of LMFC MASK RESET bit just for reference because datasheet doesn't show it?

Best Regards,

Hi Yaita,

LMFC MASK RESET has to zero for normal operation. Setting this bit to 1 is reserved for internal use.

Hi Vijay-san,

Okay, I understand LMFC MASK RESET should be zero for customer use.
