Basic Measurement System
0 = The bq78350-R1 configures the PRECHG as active low (default).
1 = The bq78350-R1 configures the PRECHG as active high, requiring an external pullup.
SLEEPCHG: CHG FET is enabled during SLEEP.
0 = CHG FET off during SLEEP (default).
1 = CHG FET remains on during SLEEP.
CHGFET: FET action on valid charge termination
0 = FET active
1 = Charging and Precharging disabled, FET off (default)
CHGIN: FET action in CHARGE INHIBIT mode
0 = FET active (default)
1 = Charging and Precharging disabled, FETs off
CHGSU: FET action in CHARGE SUSPEND mode
0 = FET active (default)
1 = Charging and Precharging disabled, FETs off
OTFET: FET action in OVERTEMPERATURE mode
0 = No FET action for overtemperature condition (default)
1 = CHG and DSG FETs will be turned off for overtemperature conditions.
KEY_EN: Enables the bq78350-R1 to use the KEYIN pin function
0 = The bq78350-R1 never uses KEYIN (default).
1 = The bq78350-R1 KEYIN is used to control the DSG FET.
PCHG_EN: Enables the bq78350-R1 to use the PRECHG pin during PRECHARGE mode
0 = The bq78350-R1 never uses PRECHG.
1 = The bq78350-R1 controls PRECHG under normal charge control algorithm (default).
2.6.3 AFE Cell Map
This register maps the cells connected to the companion AFE so that the bq78350-R1 knows cells are
present at the indicated VCx channel.

VCx: Cell connected to this node
1 = A cell is connected to this node and valid measurements are expected.
0 = A cell is NOT connected to this node.
