How to terminate unused ONOFF and PMIC_ON_REQ?

[adevries]

Hello,

My design will be powering the 8M Mini using an external PMIC, so I don't need to use the ONOFF signal or PMIC_ON_REQ signal provided on the 8M Mini. How should these signals be terminated when they are unused?

Thanks

Hi adevries

PMIC_ON_REQ may be left unconnected, ONOFF requires pullup

as described in Table 8. Reset and ON/OFF recommendations

Hi Igor,

Thanks for the response. I will do that. However, I think Figure 6-31 in the reference manual is a bit misleading. I interpreted it as ONOFF having an internal pull-up, but it would appear that is not the case.

Thanks
