We're planning a device with the following architecture:
With the VDDIO_OUT from the U12 controlling the power supply to the L6 so that when the U12 goes into deep sleep the L6 is powered off.
Code: Select all
Spi Flash | [node0] <--LINK --> [node1] <LB--LINK--LB> [node2] |_________________________| |_____| XS1-U12 XS1-L6
My question is; will the L6 correctly boot from the U12 upon waking up? I'm assuming the U12 upon waking from deep sleep loads/boots from the Flash as if it was reset and will also boot the L6 as normal, is this correct?
