9.6 Register Maps
9.6.1 Pack Configuration Register
Some bq27546-G1 pins are configured via the Pack Configuration data flash register, as indicated in Table 9.
This register is programmed/read via the methods described in the bq27546-G1 Technical Reference Manual
(SLUUB74). The register is located at Subclass = 64, offset = 0.

RESCAP = No-load rate of compensation is applied to the reserve capacity calculation. True when set.
CALEN = Calibration mode is enabled.
INTPOL = Polarity for Interrupt pin. (See INTERRUPT Mode.)
INTSEL = Interrupt Pin select: 0 = SE pin, 1 = HDQ pin. (See INTERRUPT Mode.)
RSVD = Reserved. Must be 0.
IWAKE/RSNS1/RSNS0 = These bits configure the current wake function (see Wake-Up Comparator).
GNDSEL = The ADC ground select control. The VSS (pins C1, C2) is selected as ground reference when the bit is clear.
Pin A1 is selected when the bit is set.
RFACTSTEP = Enables Ra step up/down to Max/Min Res Factor before disabling Ra updates.
SLEEP = The fuel gauge can enter sleep, if operating conditions allow. True when set. (See SLEEP Mode.)
RMFCC = RM is updated with the value from FCC, on valid charge termination. True when set.
SE_PU = Pull-up enable for SE pin. True when set (push-pull).
SE_POL = Polarity bit for SE pin. SE is active high when set (makes SE high when gauge is ready for shutdown).
SE_EN = Indicates if set the shutdown feature is enabled. True when set.
TEMPS = Selects external thermistor for Temperature() measurements. True when set.
