Bugfix: correct presentation error in tissues custom view The green vertical line in the N2/He bars show the inspired partial pressures of the respective gasses. Obviously, the tissue partial pressure is always lower on an initial descent, than the inspired partial pressure of the respective gas. Further, when for a given depth, the inspired partial pressure is equal to the tissue partial pressure, the tissue gets fully saturated, so the bars stop at the green line. For N2, a simple presentation error was present. As the body is always saturated with about 75% of N2 (according to the Buelmann algorithm), the tissue N2 was shifted left for that amount, but the inspired N2 line was not. So, the N2 green vertical line was too far to the right. Corrected this. Signed-off-by: Jan Mulder <jlmulder@xs4all.nl>

  ============================================================================== 

The bq5105x provides one status output, CHG. This output is an open-drain NMOS device that is rated to 20 V.
The open-drain FET connected to the CHG pin will be turned on whenever the output (BAT) of the charger is
enabled. As a note, the output of the charger supply will not be enabled if the VRECT-REG does not converge to the
no-load target voltage.

CHG F4 7 O Open-drain output – active when BAT is enabled. Float if not used.
