Dear Support,

The SCLK_SPMI and SDATA_SPMI pins are present on this evaluation board, and how to make these two pins output SPMI signals, such as a sleep SPMI command to a slave.

Thanks,

Jianlin

Hi Jianlin,

I think Section 4.1 and Section 2.2 of the EVM User Guide may provide the needed steps: https://www.ti.com/lit/ug/slvubx4a/slvubx4a.pdf

Best regards,

Matt

Hi Jianlin,

SPMI interface is intended to be used for multi-PMIC system. So if you want to enable SPMI in the NVM you must have another PMIC device defined as secondary to be able to have communication established.

After multi-PMIC NVM is defined communication between devices happens automatically over SPMI based on PFSM triggers and state.

There is no way to output manually anything over SPMI interface.
