Gain factor for adaptive recharge algorithm period_new=period * (
1+/-(2^-C1+2^-C2) ) Valid values for C2 is 2 to 10 Note: Rounding
may cause adaptive recharge not to start for very small values of
both Gain and Initial period. Criteria for algorithm to start is
MAX(PERIOD*2^-C1,PERIOD*2^-C2) >= 1

This register defines the maximum period that the recharge
algorithm can take, i.e. it defines the maximum number of cycles
between 2 recharges. The maximum number of cycles is specified
with a 5 bit mantissa and 3 bit exponent:
MAXCYCLES=(MAX_PER_M*16+15)*2^MAX_PER_E This field sets
the mantissa of MAXCYCLES

For recharge algorithm, PERIOD is the initial period when entering
powerdown mode. The adaptive recharge algorithm will not change
this register PERIOD will effectively be a 16 bit value coded in a 5 bit
mantissa and 3 bit exponent: This field sets the Mantissa of the
Period. PERIOD=(PER_M*16+15)*2^PER_E
