about Internal Weak Pull-Up(cyclone10LP)

Hello,

 

Tell me about the Internal Weak Pull-Up of cyclone10LP.
For before and during configuration, is weak pull-up enabled regardless of the weak pull-up resistor setting?

Hi,


Thank you for contacting Intel community.


Please explain further on your question, or you can also refer to below link:


For Cyclone 10 LP

Kindly refer to Cyclone 10 LP datasheet below:

Hello,

 

Thank you for your answer to me.
I checked Table 11 on page 13 of the Cyclone10LP Device Database.
Is the weak pull-up resistor as follows?

 

When the weak pull-up resistor is set to ON, the pull-up resistor is inserted before and during configuration, and in user mode.

When the weak pull-up resistor is set to OFF, the pull-up resistor does not enter (that is, high impedance) before and during configuration, and in all user modes.

 

best regards,
