Incremented when write retries exceeds

Maximum number of internal write retries.
Function
Compensate RemCap – the displayed
RemCap decrease only – when
Unused.
Set capacity to positive immediately
Unused.
RemCap actually equals FCC minus
capacity used minus residual capacity
due to temperature. RemCap is
compensated for temperature.
compensating, if temperature
changed causing a decrease in
residual capacity, do not let RemCap
rise to reflect this. Instead hold it
steady until discharge catches up.
This occurs so user does not see
capacity increase while discharging.
(though usable capacity may increase
if the temperature changes, user may
be confused).
Use compensated FCC – to compute
RSOC. Allows compensated RSOC
to equal 100% at full charge.
Report compensated FCC – the
compensated FCC is reported in
SBData to allow for externally
calculated RSOC.
upon charging – if discharged below
zero, this allows capacity to count up
immediately upon charging.
Learn Unconditionally – relearn FCC
no matter what. Typically a max
current and a max error limitation
occur on relearn. This removes the
limitations. Typically used for testing
only.
