IIN (#7 in sequence) is never used.
Signed is never set. Signed measurements of IBAT will halve the measuring sensitivity, and is therefore not favourable. At the moment, great currents (f.ex. if something happens with the battery) will be interpreted as negative, which might cause unfavourable behaviour during charging (depending on what PWM behaviour is defined), f.ex. ConstantCurrent() will keep increasing the PWM output. This results in an PWM controller error being flagged and the program going into error-state and eventually reinitializing.
