DESCRIPTION
Reports the firmware version on the device type
Reports the hardware version of the device type
Not to be used
Returns reset data
Not to be used
Returns previous MAC command code
Reports the chemical identifier of the Impedance Track configuration
Forces the device to measure and store the board offset
Forces the device to measure and internal CC offset
Forces the device to store the internal CC offset
Reports the data flash version on the device
Set the [FULLSLEEP] bit in Control Status register to 1
Forces CONTROL_STATUS [HIBERNATE] to 1
Forces CONTROL_STATUS [HIBERNATE] to 0
Forces CONTROL_STATUS [SHUTDOWN] to 1. SET_SHUTDOWN
enables the system to enter into SHUTDOWN mode.
Forces CONTROL_STATUS [SHUTDOWN] to 0
Forces CONTROL_STATUS [HDQIntEn] to 1
Forces CONTROL_STATUS [HDQIntEn] to 0
Calculates chemistry checksum
Forces the DOUT pin low to disable discharge
Clears DSGFETOFF, allowing DOUT to go high if no other conditions force
it low
Places the bq28z560-R1 in SEALED ACCESS mode
Enables the Impedance Track algorithm
Toggle bq28z560-R1 CALIBRATION mode
Forces a full reset of the bq28z560-R1
Exit bq28z560-R1 CALIBRATION mode
Enter bq28z560-R1 CALIBRATION mode
Reports internal CC offset in CALIBRATION mode
CONTROL_STATUS: 0x0000
Instructs the gas gauge to return status information to Control addresses 0x00/0x01. The status word includes
the following information.

DSGFETOFF = State bit indicating the DISCHARGE FET has been disabled by HOST (HOST DISCONNECT).
FAS = Status bit indicating the bq28z560-R1 is in FULL ACCESS SEALED state. Active when set.
SS = Status bit indicating the bq28z560-R1 is in the SEALED state. Active when set.
CALMODE = Status bit indicating the calibration function is active. True when set. Default is 0.
CCA =
Status bit indicating the bq28z560-R1 coulomb counter Calibration routine is active. The CCA routine takes place
approximately 1 minute after the initialization and periodically as gauging conditions change. Active when set.
BCA = Status bit indicating the bq28z560-R1 Board Calibration routine is active. Active when set.
CSV = Status bit indicating a valid data flash checksum has been generated. Active when set.
