i'm writing bare-metal code for the FLPR (which was loaded by a bare-metal launcher running on the M33)....
when my FLPR code "idles" using the WFI instruction, power consumptions remains around 500uA -- which is consistent with what i've read elsewhere....
but then, i saw some notes about "VPR hibernate" in the errata and want to learn more about this capability....
there is also reference to the "VPR context save address", which seems related....
where can i learn more????
my objective is to use the FLPR for an extended period of time, in which the CPU activity alternates with periods of sleep....
ideally, sleep should be in the ~1uA range -- not 500uA.... are there any examples illustrating this use-case???
