Can i.MX6ULL VDD_SNVS_IN and VDDHIGH_IN be combine?

[m_c]

In the 4.1.3 table 10 of i.MX6ULL data sheet <http://nxp.com/doc/imx6ulliec>, it said VDD_SNVS_IN and VDDHIGH_IN can be combined if doesn't require keeping real time and other data on OFF state.

In the 4.2.1, it said VDD_SNVS_IN supply must be turned on before any other power supply.

So, is it still fulfill the requirement of power-up sequence if combine VDD_SNVS_IN and VDDHIGH_IN?

Hello,

   Yes, it is possible to connect  VDD_SNVS_IN and VDDHIGH_IN together,

assuming they are still should be applied before any other voltages. 

Have a great day,

Yuri
