Push-pull output to indicate the boot switch setting of the jig cable
IO supply voltage. This is the internal supply voltage for the BOOT and
INTB outputs. It can supply the external pull-up voltages for the JIG pin
and the I 2 C bus outside the 34827. This pin also functions as the
hardware reset to the IC.
