The Initial Settings box programs selected registers of the bq2014H. The value
can be entered in the selected box and written to the device by depressing the
Write Settings to Device button.
The screen also displays how pins 2 (Prog1) through 7 (Prog6) are pro-
grammed. The Reset Device button initializes the bq2014H with the pro-
grammed settings. A device reset can also be performed by writing LMD = 0
and then PPFC = 0 using the Data screen.
The Table Data box interprets the programming for self-discharge and display
modes. It also shows the programmed full battery capacity in terms of mVh and
mAh (mAh = mVh/Rsns). The programmed full capacity or count (PFC) is set
by the programming of pins 2–5.
