powerful. Since the PIC has avilable weak pull-ups on the gpio lines, the
open-drain state outputs from the regulator don't need resistors to be read.

+- v1.0 and v1.1 boards have a minor error in that the v_lipo sampling resistors
+ are on "the wrong side of the cut" if you try to use a separate pyro battery.
+ The workaround is to cut that trace and put in a jumper, which pretty much
+ requires "return to Bdale for rework". We should fix this for a future PCB
+ revision.
